Oxford theses

The Bodleian Libraries’ thesis collection holds every DPhil thesis deposited at the University of Oxford since the degree began in its present form in 1917. Our oldest theses date from the early 1920s. We also have substantial holdings of MLitt theses, for which deposit became compulsory in 1953, and MPhil theses.

Since 2007 it has been a mandatory requirement for students to deposit an electronic copy of their DPhil thesis in the Oxford University Research Archive (ORA) , in addition to the deposit of a paper copy – the copy of record. Since the COVID pandemic, the requirement of a paper copy has been removed and the ORA copy has become the copy of record. Hardcopy theses are now only deposited under exceptional circumstances. 

ORA provides full-text PDF copies of most recent DPhil theses, and some earlier BLitt/MLitt theses. Find out more about Oxford Digital Theses, and depositing with ORA .

Finding Oxford theses

The following theses are catalogued on SOLO (the University libraries’ resource discovery tool) :

• DPhil and BLitt and MLitt theses
• BPhil and MPhil theses 
• Science theses

SOLO collates search results from several sources.

How to search for Oxford theses on SOLO

To search for theses in the Oxford collections on SOLO :

• navigate to the SOLO homepage
• click on the 'Advanced Search' button
• click the 'Material Type' menu and choose the 'Dissertations' option

Searching by shelfmarks

If you are searching using the shelfmark, please make sure you include the dots in your search (e.g. D.Phil.). Records will not be returned if they are left out.

Oxford University Research Archive (ORA)

ORA was established in 2007 as a permanent and secure online archive of research produced by members of the University of Oxford. It is now mandatory for students completing a research degree at the University to deposit an electronic copy of their thesis in this archive. 

Authors can select immediate release on ORA, or apply a 1-year or 3-year embargo period. The embargo period would enable them to publish all or part of their research elsewhere if they wish. 

Theses held in ORA are searchable via  SOLO , as well as external services such as EThOS and Google Scholar. For more information, visit the Oxford digital theses guide , and see below for guidance on searching in ORA.

Preparation and Submission of your Thesis

IMPORTANT - When preparing your thesis please ensure that you have taken into account any copyright or sensitive content issues, and dealt with them appropriately. 

COVID-19  Additional academic support – Supporting Students to Submission

Additional academic support is available for postgraduate research students impacted by the pandemic. If your research has been disrupted by COVID-19, it will now be possible to have this taken into account in viva examinations.

Tips on planning your thesis

At an early stage you should:

• Prepare a detailed work plan for your research in consultation with your supervisor.
• Build some flexibility into your plan. It is difficult to give general advice about the allocation of time on theory‑oriented projects, because the nature of these is so variable. In the case of experiment‑based research projects, you should normally allow up to six months to write a DPhil thesis, or three to four months for a corresponding MSc by Research thesis.
• Consider attending available skills training courses, for example  Thesis and Report Writing .

It is not advisable to leave all the writing to the end, for several reasons:

• You will need practice at writing over a period of time in order to develop a good style.
• There will inevitably be hold‑ups in experimental work and it is better to use that time to work on part of your thesis, rather than to waste it. If you do some writing earlier the final completion of your thesis will not seem such a daunting task.
• Approaching your submission date will become more stressful than necessary.

About your thesis

The best way to find out what is required for a successful thesis in your subject area is to look at some written in recent years. You should obviously look particularly closely at theses written by previous members of your own research group, which are available in the University library.

The formal requirements for obtaining your degree are set out in detail in the ‘ Examination Regulations ’. The standard required for success in the DPhil examination is defined as follows: that the student present a significant and substantial piece of research, of a kind which might reasonably be expected of a capable and diligent student after three or at most four years of full‑time study in the case of a full-time student, or eight years in the case of a part-time student. For the MSc by Research the standard required is that the candidate should have made a worthwhile contribution to knowledge or understanding of the relevant field of learning after a minimum of one year or two years of full-time study.

Thesis structure - Integrated Thesis

Subject to approval, students registered on research programmes (DPhil, MSc (Res) and CDTs) in the following departments may submit an integrated thesis rather than a conventional thesis: Biology, Chemistry, Earth Sciences, Engineering Science and Statistics. Where a student is admitted to an interdisciplinary doctoral training programme (CDT/DTP), the regulations for the department that the student is hosted in will therefore determine whether an integrated thesis may be applied for.

An integrated thesis may either be a hybrid of conventional chapters and high-quality scientific papers, or be fully paper-based. Regardless of the format, the content of the thesis should reflect the amount, originality and level of work expected for a conventional thesis. It should not be assumed that the act of publication (in whatever form) means the work is of suitable academic quality and content for inclusion in a thesis, and students should discuss all papers in detail with their supervisor before including. It would be anticipated that the candidate would be a lead contributor, rather than a minor author, on at least some of the papers in order to consider this format. There is no minimum, or maximum, number of papers a candidate is expected/allowed to include as part of such a thesis and it will remain a matter for the examiners to conclude whether the contributions are equivalent to that which would be expected of a standard DPhil.

Any papers utilised must concern a common subject, constitute a continuous theme and conform to the following guidelines:

 (i) If a candidate for the Degree of Doctor of Philosophy wishes to be examined through an integrated thesis (in the departments listed above), they should apply for permission to be examined in this way when they apply for confirmation of status, as detailed in the relevant departmental handbook. A candidate for the Degree of Master of Science by Research should normally apply to the DGS for permission to be examined in this way six months before submitting their papers for examination. To revert to being examined by a conventional thesis rather than an integrated thesis, the candidate must inform their department of the change as detailed in the relevant departmental handbook.

(ii) Work can be included regardless of its acceptance status for publication but candidates may be questioned on the publication status of their work by the examiners.

(iii) Any submitted/published papers should relate directly to the candidate’s approved field of study, and should have been written whilst holding the status of PRS or a student for the MSc (by Research), or DPhil.

(iv) The collection of papers must include a separate introduction, a full literature review, discussion and a conclusion, so that the integrated thesis can be read as a single, coherent document.

(v) The candidate must ensure all matters of copyright are addressed before a paper’s inclusion. A pre-print version of any published papers should be included as standard.

(vi) Joint/multi-authored papers are common in science based subjects and thus acceptable if the candidate can both defend the paper in full and provide a written statement of authorship, agreed by all authors, that certifies the extent of the candidate’s own contribution. A standard template is available for this purpose.

• Download the Statement of Authorship template as a Word document
• View the Statement of Authorship template as a webpage  

The length and scope of theses, including word limits for each subject area in the Division are set out in Departmental guidelines.

In all departments, if some part of the thesis is not solely your work or has been carried out in collaboration with one or more persons, you should also submit a clear statement of the extent of your contribution.

• Download the guidance for submitting an Integrated Thesis as a Word document
• View the guidance for submitting an Integrated Thesis as a webpage

Thesis page and word limits

Several departments place a word limit or page limit on theses. Details can be found in the  Examination Regulations  or  GSO.20a Notes of Guidance for Research Examinations .

Permission to exceed the page and word limits

Should you need to exceed your word/page limit you must seek approval from the Director of Graduate Studies in your department. You and your supervisor must submit a letter/email requesting approval, giving reasons why it is necessary to exceed the limit. This must be sent to the MPLS Graduate Office ( [email protected] ).

Proof-reading

It is your responsibility to ensure your thesis has been adequately proof-read before it is submitted.  Your supervisor may alert you if they feel further proof-reading is needed, but it is not their job to do the proof-reading for you.  You should proof-read your own work, as this is an essential skill in the academic writing process. However, for longer pieces of work it is considered acceptable for students to seek the help of a third party for proof-reading. Such third parties can be professional proof-readers, fellow students, friends or family members (students should bear in mind the terms of any agreements with an outside body or sponsor governing supply of confidential material or the disclosure of research results described in the thesis).   Proof-reading assistance may also be provided as a reasonable adjustment for disability.    Your thesis may be rejected by the examiners if it has not been adequately proof-read.  

See the University’s Policy on the Use of Third Party Proof-readers . The MPLS Division offers training in proof-reading as part of its Scientific Writing training programmes.

Examiners and Submission Dates

You are strongly advised to apply for the appointment of examiners at least four to six weeks before you submit your thesis.

Appointing examiners for your thesis

Approval of the proposed names of examiners rests with the Director of Graduate Studies. Two examiners are normally appointed. It is usual for one of the examiners to be a senior member of Oxford University (the ‘internal examiner’) and the other to be from another research organisation (the ‘external examiner’). The divisional board will not normally appoint as examiners individuals previously closely associated with the candidate or their work, representatives of any organisation sponsoring the candidate’s research, or former colleagues of a candidate. Your supervisor will make suggestions regarding the names of possible examiners. Before doing so, your supervisor must consult with you, in order to find out if you have any special views on the appointment of particular examiners. Your supervisor is also allowed to consult informally with the potential examiners before making formal suggestions. Such informal consultation is usually desirable, and is intended to determine whether the people concerned are willing in principle to act, and if so, whether they could carry out the examination within a reasonable period of time. (For example, there may be constraints if you have to return to your home country, or take up employment on a specific date).

See information on examiner conflicts of interest , under section 7.3.3 Examiners.

What forms do I need to complete?

You will need to complete the online  GSO.3 form. Supervisors complete the section indicating names of the proposed examiners, and they should provide alternatives in case the preferred examiners decline to act.

Timing for appointment of examiners

You are advised to submit your appointment of examiners form in advance of submitting your thesis to avoid delays with your examination process. Ideally you should apply for the appointment of examiners at least 4-6 weeks before you expect to submit your thesis for examination.

There are currently no University regulations requiring examination to take place within a certain time limit after thesis submission. However, your examiners would normally be expected to hold your viva within 3 months. If you need to have your examination sooner than this, you may apply for an early viva , by completing the 'Application for a time specific examination' section on the appointment of examiners form, this section must be endorsed by your supervisor and DGS in addition to their approval in the main body of the form. The request must be made at the time of completing and submitting the appointment of examiners form, it cannot be done after this.

Please bear in mind that the examination date requested must not be earlier than one calendar month after the date on which the thesis has been received by the Research Degrees Team or after the date on which the examiners have formally agreed to act, whichever is the latest. The actual date of the examination will depend primarily on the availability of both examiners. In the Long Vacation, a longer time is normally required. It is therefore essential that you leave sufficient time for your forms to be formally approved, and for your examiners to be formally invited.  If sufficient time has not be given this could impact on your early examination request .

If, for any reason, examiners wish to hold a viva within four weeks of receiving their copy of the thesis, permission must be sought from the Director of Graduate Studies. The internal examiner will need to give details of the proposed arrangement and the reasons for the request. Under no circumstances will a viva be permitted to take place within 14 days of receipt of the thesis by the examiners.

Special considerations

Your supervisor is permitted to indicate to the Director of Graduate Studies if there are any special factors which should be taken into account in the conduct of your examination. For example, a scientific paper may have been produced by another researcher which affects the content of your thesis, but which was published too late for you to take into account. The Director of Graduate Studies will also need to be told of any special circumstances you may require or need to inform your examiners of which may affect your performance in an oral examination, or if any part of your work must be regarded as confidential. The Director of Graduate Studies will then forward (via the Graduate Office), any appropriate information that they think should be provided to the examiners. The Graduate Office will also seek approval from the Proctors Office if required.

Change of thesis title

If during your studies you want to change the title or subject of your thesis, you must obtain the approval of the Director of Graduate Studies using the online form GSO.6 . If you are requesting the change at the time of submitting your thesis, you may do this on the application for appointment of examiners form. A change of title is quite straightforward; it is common for students to begin with a very general title, and then to replace it with a more specific one shortly before submitting their thesis. Providing your supervisor certifies that the new title lies within the original topic, approval will be automatic. A change of the subject of your research requires more detailed consideration, because there may be doubt as to whether you can complete the new project within the original time‑scale.

If following your examination your examiners recommend that your thesis title be changed, you will need to complete a change of thesis title form to ensure that your record is updated accordingly.

From MT19 y ou must submit your digital examiners’ copy of your thesis online, via the Research Thesis Digital Submission (RTDS) portal, no later than the last day of the vacation immediately following the term in which your application for the appointment of examiners was made.   If you fail to submit by this date your application will be cancelled and you will have to reapply for appointment of examiners when you are ready to submit. Y our thesis should not be submitted until your application for confirmation of status has been approved (this applies to DPhil students only) . For MSc by Research students you should ensure that your transfer of status has been completed .

If you are funded on a research council studentship, you will have a recommended end-date before which your thesis must be submitted. If you do not know this date, please consult your supervisor.

Please note that you must not submit copies of your thesis directly to your examiners as this could result in your examinations being declared void and you could be referred to the University Proctors.

Other Term-time Courses

Further Honours School

All History finalists and some joint-schools students write a 12,000-word thesis on a topic of their own devising. Many undergraduates find this to be the most satisfying work they do in their History degree.

The thesis offers you the opportunity to engage in primary research on a subject of your own devising, and to work out arguments which are entirely your own, not a synthesis of the conclusions of others. It enables you to work as a historical scholar in your own right and to taste the kind of academic work undertaken professionally by your tutors. For those who continue as graduate historians, the thesis will represent a first opportunity to test their abilities as creative and independent researchers, able to define and explore a historical problem on a large scale. For others a successfully accomplished thesis is a clear indication to employers and the outside world that they possess a capacity for organization, selfdiscipline and the ability to structure a substantial and complex piece of research on their own initiative. Some undergraduate theses are so good that they are ready to be published as they stand. But almost all theses give their authors considerable personal satisfaction, and will be looked back on with pride long after the authors have left Oxford and the study of History behind.

Teaching: The Faculty provides an initial lecture on framing a topic in Hilary Term of the second year, and the Thesis Fair early in Trinity Term to help suggest sources from a wide range of fields. At total of five hours of advice from college tutors and a specialist supervisor are permitted across the second and third years.

Introduction to Dissertation 

OMMS and Part C students are required to undertake a dissertation worth two units as part of their degree programme. This can be either a mathematics dissertation or a statistics dissertation. 

The dissertation will entail investigating a topic in an area of the Mathematical Sciences under the guidance of a dissertation supervisor. This will culminate in a written dissertation with a word limit of 7,500 words, which usually equates to 25-35 pages. It is expected that students embarking on a dissertation will be working on it over Christmas vacation, Hilary Term and Easter vacation for submission in early Trinity Term.

Students completing a dissertation may request a book for consultation if it is held only by the Whitehead Library (and not held in the RSL, their College library or as an e-book) by emailing the Librarian at @email .

The book will be sent to the RSL where it can be consulted for reference, not borrowing.   Please see further information  here . 

Timetable for Dissertations

Choosing a topic.

Following the Dissertation Information Session, a list of potential dissertation topics will be published below. Each topic will be accompanied by a short abstract outlining the project with details on necessary pre-requisite knowledge and the maximum number of students who will be able to take each topic. You will be asked to complete an online form, ranking 5 of the topics. Please note that Maths Part C students are only permitted to chose a maximum of three statistics topics. You will be notified of which project you have been allocated by the end of week 5.

Oral Presentation

Each student is required to give an oral presentation to their supervisors and at least one other person with some knowledge of the field of the dissertation. These will usually take place in the final two weeks of Hilary Term. The presentation does not count towards the final assessment of the project, however, it will give you an opportunity to practice your presentation skills which will prove useful in your later careers.

Doctoral Theses

High-fidelity, near-field microwave gates in a cryogenic surface trap marius weber 2022.

Implementation of Mølmer-Sørensen two-qubit gates on 43 Ca + hyperfine clock qubits in a cryogenic (≈25K) surface trap, driven by near-field microwaves. We achieve gate durations of 154µs (with 1.0(2)% error) and 331µs (0.5(1)% error), which approaches the performance of typical laser-driven gates. In the 331µs gate, we demonstrate a new Walsh-modulated dynamical decoupling scheme which suppresses errors due to fluctuations in the qubit frequency as well as imperfections in the decoupling drive itself. Development of an ion transport toolbox, with demonstrations of splitting and merging operations in two different traps.

Device-independent key distribution between trapped-ion quantum network nodes David Nadlinger, 2022

Implementation of a complete protocol for device-independent quantum key distribution over a quantum network link, resulting in the generation of a 95884-bit shared private key, after 8.5 hours of run time. This is enabled by the high-rate (100s -1 ), high-fidelity [96.0(1)%] generation of Bell states between remote trapped-ion qubits, yielding a detection-loophole-free CHSH inequality violation of 2.677(6) and quantum bit error rate of 1.44(2)%, both of which are stable during the generation of millions of Bell pairs. We also introduce a versatile method for micromotion compensation using time-stamped photon detection; we achieve a sensitivity to stray electric fields of 0.1 Vm -1 /\(\sqrt{\rm Hz}\). 

An elementary quantum network of entangled optical atomic clocks Bethan Nichol, 2022

Demonstration of entanglement-enhanced frequency comparison of two optical atomic clocks based on the 674nm quadrupole transition of 88 Sr + ions, which are linked by a quantum-optical fibre link (\(\approx 2\)m long). We show that the use of an entangled state reduces the measurement uncertainty by nearly \(\sqrt{2}\), the value expected for the Heisenberg Limit. Today's optical clocks are typically limited by dephasing of the probe laser; in this regime, we find that entanglement yields a factor 2 reduction in the measurement uncertainty compared to conventional correlation spectroscopy techniques. We demonstrate this enhancement for the measurement of a frequency shift applied to one of the clocks.

A cryogenic trap for microwave-driven quantum logic using 43 Ca + ions Clemens L ö schnauer, 2021

Development of single and two-qubit operations for a new hyperfine atomic clock qubit, operating at 28.8mT in 43 Ca + , in a cryogenic surface-electrode trap. A single ion is laser-cooled to 0.5mK, close to the Doppler limit, by exploiting two-photon dark resonances that form between fine-structure levels. Resolved-sideband cooling on a Raman transition is used to cool the two-ion radial motional mode to an average occupation number \(\bar{n}=0.08\) . Spin-motion entanglement driven by near-field microwaves is used to diagnose the Mølmer–Sørensen interaction. Initial two-qubit gate attempts give a fidelity 0.77(2).

Benchmarking memory and logic gates for trapped-ion quantum computing Amy Hughes, 2021

Characterisation of the memory performance of a 43 Ca + clock qubit: randomised benchmarking is used to directly measure errors as small as 1.2(7) × 10 −6 after a storage time of 1 ms. The memory error remains < 10 −4 for up to 50 ms with no additional dynamical decoupling, or < 10 −3 for up to 2 seconds with a simple CPMG sequence. Comparison of different implementations of mixed-element two-qubit gates on a  43 Ca + - 88 Sr + crystal: a light-shift gate with a fidelity of 99.8(1)% or 99.7(1)%, measured using partial state tomography or interleaved randomised benchmarking respectively, and several varieties of Mølmer–Sørensen gates with measured fidelities of up to 99.6(2)%.

An entangled state fidelity of up to 99.8% is achieved, comparable to that of the best same-species gates. A same-species Sr-Sr gate is also demonstrated, using the 674nm S-D quadrupole transition, with fidelity 96%.

Probing qubit memory errors at the 10 −5 level James Tarlton, 2018

Direct measurement of qubit memory errors in a calcium-43 "atomic clock" qubit. Randomized memory benchmarking is used to measure the memory error of a single qubit down to the few 10 -6 level. The error is found to remain below the 10 -3 level for up to 400ms. Surface trap designs for near-field microwave-driven two-qubit gates are explored.

A high-fidelity microwave driven two-qubit quantum logic gate in 43 Ca + Martin Sepiol, 2016

Experimental implementation of a microwave-driven two-qubit quantum logic gate in a room-temperature microfabricated surface ion trap. The gate scheme involves dynamical decoupling methods, which stabilise the qubits against fluctuations of the motional mode frequency and fluctuating energy shifts, and avoid the need to null the microwave field. The gate is applied directly to hyperfine "atomic clock" qubits in 43 Ca + using the near-field microwave magnetic field gradient produced by an integrated trap electrode. The achieved gate fidelity is 99.7(1)%, after accounting for state preparation and measurement errors.

Referencing styles

Author-date citations (Harvard) Numbered notes Numbered reference citations (Vancouver) OSCOLA

Introduction

Source references are vital to academic works (both print and digital) and so it is essential that they are clear, complete, and consistently formatted. Online bibliographical material is hyperlinked to provide readers with instant access to relevant sources or additional information.

Reference styles vary greatly across disciplines. This section details the main reference styles supported by OUP (Harvard, Vancouver, and OSCOLA) and provides examples that you can follow. If you are in doubt, your OUP editorial contact will be able to advise you on the best citation system for your text.

Author-date citations (Harvard)

The author-date style is an efficient and clear method of providing citations to published sources, which appear in a reference list at the end of the chapter or book. No superscripts are used, which means that reordering of the text does not require renumbering of notes. Instead of superscript numbers, a parenthetical citation (consisting of author name and date of publication) appears in the text and leads the reader to a full entry in a reference list that appears at the end of the chapter or book.

The method works particularly well when most of your citations are to published books or journal articles. It works less well if you are citing a lot of unauthored material or untraditional sources. Unlike numbered notes, author-date citations cannot accommodate translations or commentary outside the main text, although it is possible to combine author-date citations (for bibliographic citations) with numbered notes (for explanatory text).

In-text citation

References are cited within the text by including the author’s last name and a date parenthetically. A page number can be added if needed. If the author’s name appears in the sentence containing the citation, you need only use the date. Complete bibliographical reference information is listed at the end of the chapter or text.

Up to two author names can be used in the in-text citation. When citing a work with three or more authors, use the first author’s last name plus ‘et al.’

If you cite multiple references by the same author that were published in the same year, distinguish between them by adding labels (e.g. ‘a’ and ‘b’) to the year, in both the citation and the reference list.

Structure of the reference list

The reference list appears at the end of the chapter or text in alphabetical order. The name of the first author is inverted. In science literature, initials are often used in place of author first names.

The bibliographic elements listed below are required for the most common types of reference citations. Additional elements are mentioned that may be optional or to be used in only certain instances (e.g. a page number or other locator that is required if you are quoting a precise part of a large work, but not if the reference is to the work as a whole). Consistency in application is important.

Do not use long dashes (“—") to substitute for the name of an author who is identified in the bibliography due to how that entry will be linked in digital versions. Because the entry may not appear immediately following the entry with the full name, repeat the name in full.

Psychoanalytic studies, along with other literary and cultural texts, not only contribute to the new discourse of the jungle but also reflect the imperialist history that brings West Europeans and Americans into contact with the geographic jungles of India, Africa, and other parts of the world (Rogers et al. 2010, 1). This colonial context needs to be sketched here as well in order to reveal how the birth of the jungle eventually produces new constructions of sexuality in the United States. Billops (1999a) notes that the word ‘jungle’ comes from the Hindi and Marathi word jangal, meaning ‘desert’, ‘waste’, ‘forest’; as well as from the Sanskrit jangala, meaning ‘dry’, ‘dry ground’, or ‘desert’. Its first appearance in English is in 1776, with its meaning already shifted towards what might be more recognizable today: ‘Land overgrown with underwood, long grass, or tangled vegetation; also, the luxuriant and often almost impenetrable growth of vegetation covering such a tract’ (Dreft and Smithers 1978, 87). Brought into English as a result of an imperialist presence in India, ‘jungle’ is intimately related to the larger rise of Western imperialism around the world, particularly in the nineteenth century (Billops 1999b). Western powers such as Britain and France went from controlling 35 per cent of the earth’s surface in 1800 to, by 1914, ‘a grand total of roughly 85 per cent of the earth as colonies, protectorates, dependencies, dominions, and commonwealths’ (Said 1993, ch.2, ‘Colonial impacts’).

Reference list vs. bibliography

Note that a reference list in the author-date system can contain only items that are actually cited in the work. The reference list must contain all of those items. This differs from a bibliography in the numbered-note system, which can contain both cited items and items of interest that have not been specifically cited. If there are uncited works that you would like to draw to the reader’s attention, these can be placed after the references in a separate listed titled ‘Further reading’.

Numbered notes

Using numbered notes is a common method of citing sources, particularly in the humanities. Sequential superscript numbers appear in the text to direct the reader to bibliographic or explanatory information that appears in a note.

This is a flexible style that allows authors to combine bibliographic information with annotation, translation, or other commentary. Scholars who frequently cite unpublished material will find numbered notes more useful than author-date citations.

Endnotes or footnotes?

In print publishing, notes can be placed at the bottom of the page as footnotes or at the end of a chapter or book in a separate section as endnotes.

Footnotes are preferred in cases where the information in the note is important enough that readers need it to fully engage with the material. Please note that in a digital context, footnotes in the traditional sense are not possible. Depending on the format, footnotes can appear at the end of a section or chapter, or they may be viewed by clicking or hovering over the superscript numbers in the text to display individual footnotes.

Endnotes are a better choice in print if the material in the notes does not need immediate engagement by the reader. For digital publications where individual chapters may be made available to readers, the notes should appear with the chapter, rather than separately at the end of the work. This varies according to discipline, so please consult your OUP editorial contact if you are unsure.

The formatting of bibliographic information is identical for footnotes and endnotes.

Please use the following guidance:

• Numbered notes appear sequentially in the text as superscripts, ideally at the end of a sentence, following the closing punctuation.
• Use Arabic numerals.
• Numbers should restart at 1 at the beginning of each chapter and run consecutively to the end of each chapter. Do not start renumbering within a chapter (e.g. per page or per double-page spread) or use asterisks, as this will cause confusion in a digital environment.
• Do not number the notes continuously throughout a book, because a later change would necessitate extensive renumbering.

Note structure and format

Required bibliographic elements are given below for the most common types of reference citations, along with optional elements that if used, must be consistent.

• Page numbers are useful locators when referencing in print publications.
• Give page ranges using the fewest number of figures as possible (e.g. pp. 126–27, not pp. 126–127).
• When referencing a digital publication, you may not have access to a print page number. Cite a specific locator (e.g. chapter titles and sub-headings). Do not use location numbers from a proprietary e-reader (e.g. Kindle location numbers).
• Edition numbers are not required when citing a first edition but are necessary for subsequent editions.

Numbered notes in combination with a bibliography

It is possible to combine notes and bibliography so that all the notes, including the first reference, are short citations that lead the reader to a full citation in the bibliography. This system results in shorter notes and less work for the reader, since complete information is easily available in the alphabetical bibliography and need not be hunted for through all the chapter notes. This requires that all cited sources appear in a bibliography, which can also contain works that are not cited but are germane to the topic.

Structure of a bibliography entry

Bibliographies are structured similarly to notes, but there are some important differences. The first author name (and only the first) is inverted for alphabetization. Punctuation format also varies slightly between notes and bibliographic entries.

Do not use long dashes (e.g. “—") to substitute for an author’s name if it is repeated in the bibliography. Repeat the name in full because in a digital version, the shortened entry may not follow the complete one immediately.

Numbered reference citations (Vancouver)

Numbered reference citations (also known as author–number or Vancouver references) are used in scientific and medical texts. In this system, each reference used is assigned a number. When that reference is cited in the text, its number appears, either in parentheses or brackets or as a superscript. All cited references appear in a numbered reference list at the end of the chapter or book.

An advantage of numbered references over the author–date style is that less space in the main text is required for in-text citations. The system also avoids ambiguity in the case of two works by the same author published the same year, an occasional issue in author–date citations. A disadvantage is that late addition or removal of references usually requires renumbering of both the reference list and the citations. Numbered reference citations cannot be used to provide commentary or other explanatory material to the text.

References are cited within the text by using a number in a superscript, in parentheses, or in square brackets. Although each of these variants is acceptable, only one can be used in a single text. The examples in this guide will enclose citation numbers in parentheses. Note that although citations are numbered in the order of their first appearance in the text, non-consecutive note numbers are possible, to allow references to be cited more than once. Citations can take the form of a range: for example (4–7) would cite references 4, 5, 6, and 7 simultaneously. If it is necessary to cite specific page numbers that are not present in the reference list, page numbers can be inserted into the citation: for example (4p6, 5pp1–11).

Please note the following:

• Author first names are usually given as initials only, with no full stops (e.g. “AN” not “A.N.”) between initials. In the case of multiple authors, you can list up to six full names; for more than six authors, list the first three plus ‘et al’. All author names are inverted (i.e. last name, first name).
• Names of journals can be abbreviated, as in the examples in this section, but must follow the standard abbreviations used by PubMed. Journal article titles are given without quotation marks and in sentence-style capitalization.
• Do not use long dashes (e.g. “—") to substitute for the name of an author whose name is repeated in the bibliography. Repeat the name in full because linking in a digital publication may not immediately follow the entry with the full name.
• Citations are numbered in the order in which they first appear in the text.

Required bibliographic elements are given below for the most common types of reference citations, along with optional elements (if used, be consistent). Other elements below are required if applicable (for example, you need a page number or other locator if you are quoting a precise part of a large work, but you can skip it if the reference is to the work as a whole).

Example: Numbered reference citations and reference list—British style

Colorectal cancer (cRc) is one of the most common malignancies and the second leading cause of death from cancer in Europe and North America (1). While early stage cRc is associated with an excellent 5-year survival rate (90% for localized disease), approximately 20% of patients present with metastatic disease, and many patients diagnosed with stage ii or iii cancer will experience a recurrence and develop distant metastases (2). At present, established clinico-pathological criteria are used to estimate risks of recurrence in stage ii and iii disease, and this is routinely used in the selection of patients or adjuvant systemic therapy following surgical resection. The clinical outcome of patients who receive such adjuvant treatment can, however, vary widely, when additional molecular factors are taken into consideration. Identification of novel prognostic markers is, therefore, vital in improving the prognosis of this disease (3). One of the recently described substances important for angiogenesis is endoglin. Endoglin, also known as cD105, is a receptor for transforming growth factor-ß1 molecule, which binds preferentially to the activated endothelial cells that participate in tumour angiogenesis, with weak or negative expression in vascular endothelium of normal tissues. Endoglin is induced by hypoxia. Therefore, it is very useful for assessment of neo-angiogenesis of malignant neoplasms (4–6). Many reports indicate that endoglin assessed immunohistochemically in colorectal cancer correlates not only with tumour microvessel density, but also with survival. It has also been reported as a valuable parameter predicting patients having an increased risk of developing metastatic disease. Endoglin is expressed not only on cell surfaces since its soluble form (sol-end) can be detected also in blood (4–7). A few studies evaluated the clinical significance of elevated sol-end levels in colorectal cancer patients (7).
