Table of Contents

Entire Website - No Separate Pages or Sections

Page or Section from a Website

Note: All citations should be double spaced and have a hanging indent in a Reference List.

A "hanging indent" means that each subsequent line after the first line of your citation should be indented by 0.5 inches.

This Microsoft support page contains instructions about how to format a hanging indent in a paper.

It can sometimes be difficult to find out who the author of a website is. Remember that an author can be a corporation or group, not only a specific person. Author information can sometimes be found under an "About" section on a website.

If there is no known author, start the citation with the title of the website instead.

The best date to use for a website is the date that the content was last updated. Otherwise look for a copyright or original publication date. Unfortunately this information may not be provided or may be hard to find. Often date information is put on the bottom of the pages of a website.

If you do not know the complete date, put as much information as you can find. For example you may have a year but no month or day.

If an original publication date and a last updated date are provided, use the last updated date. If the more current date is "last reviewed" instead of "last updated," use the original publication date (since the review may not have changed the content).

If there is no date provided, put the letters (n.d.) in round brackets where you'd normally put the date.

Titles should be italicized when the document stands alone (e.g. books, reports, websites, etc.), but not when it is part of a greater whole (e.g. chapters, articles, webpages, etc.).

Website Name

Provide website names in title case without italics after titles of work. Include a period after the website name, followed by the URL. When the author of the work is the same as the website name, omit the site name from the reference.

Retrieval Date

If the content of a website is likely to change over time (e.g. Wikis), you must provide the date you last visited the website.

If a URL is too long to fit onto one line, try to break it at a slash (/).

Entire Website

Note: If you are quoting or paraphrasing part of a website, you should create a reference for a Page or Section. If you mention a website in general, do not create a reference list entry or an in-text citation. Instead, include the name of the website in the text and provide the URL in parentheses.

The Department of Justice has a site called ReportCrime.gov (https://www.reportcrime.gov/) to help people identify and report crimes in their area.

Note : If you cite multiple webpages from a website, create a reference for each. Include the date you retrieved the information if the content is likely to change over time.

Created by a Corporate or Group Author

Corporation/Group/Organization's Name. (Year website was last updated/published, Month Day if given). Title of page: Subtitle (if any). Website Name. URL

Example in which the content is unlikely to change over time:

American Society for the Prevention of Cruelty to Animals. (2019, November 21). Justice served: Case closed for over 40 dogfighting victims . https://www.aspca.org/news/justice-served-case-closed-over-40-dogfighting-victims

Example in which the content is likely to change over time:

Adidas. (2020). Sustainability . Retrieved January 23, 2020, from https://www.adidas.com/us/sustainability

Note: When the author and site name are the same, omit the site name in the reference.

In-Text Paraphrase:

(Corporation/Group's Name, Year)

Example: (Adidas, 2020)

In-Text Quote:

(Corporation/Group's Name, year, Section Name section, para. Paragraph Number if more than one paragraph in section)

Example: (Adidas, 2020, Sustainability section, para. 1)

Note: When there are no visible page numbers or paragraph numbers, you may cite the section heading and the number of the paragraph in that section to identify where your quote came from.

Abbreviating Corporation/Group Author Name in In-Text citations:

Author names for corporations/groups can often be abbreviated. The first time you refer to the author, provide the full name, along with the abbreviation.

If the group name appears in the text of your paper, include the abbreviation in the in-text parenthetical citation:

Example: The American Society for the Prevention of Cruelty to Animals (ASPCA, 2019) assisted in the rescue of 40 dogs.

If the group name first appears within a parenthetical citation, include the full group name as well as the abbreviation in square brackets:

Example: Forty dogs were rescued in Bendena, Kansas (American Society for the Prevention of Cruelty to Animals [ASPCA], 2019).

Provide the full group name (without an abbreviation) in the reference list entry: 

Created by an Individual Author 

Author's Last Name, First Initial. Second Initial if Given. (Year website was last updated/published, Month Day if given). Title of page: Subtitle (if any). Website Name. URL

Price, D. (2018, March 23). Laziness does not exist . Medium. https://humanparts.medium.com/laziness-does-not-exist-3af27e312d01

Shillam, S. (2018). Message from the Dean . University of Portland. Retrieved October 1, 2018, from https://nursing.up.edu/about/index.html

(Author Last Name, Year)

Example: (Shillam, 2018)

(Author Last Name, Year, Section Name section, para. Paragraph Number if more than one paragraph in section)

Example: (Shillam, 2018, Message from the dean section, para. 2)

Created by an Unknown Author 

Title of page: Subtitle (if any). (Year website was last updated/published, Month Day if given). Website Name. URL

Example in which the content is unlikely to change over time (because the restaurant has closed) :

Jarra's Ethiopian Restaurant [Reviews]. (2012, November 9). Yelp. https://www.yelp.com/biz/jarras-ethiopian-restaurant-portland

Powell's City of Books [Reviews]. (2020, February 25). Yelp. Retrieved February 28, 2020, from https://www.yelp.com/biz/powells-city-of-books-portland-4

("Title," Year)

Example: ("Powell's City of Books," 2020)

("Title," Year, Section Name section, para. Paragraph Number if more than one paragraph in section)

Example: ("Powell's City of Books," 2020, Review Highlights)

Note: When there are no visible page numbers or paragraph numbers, you may cite the section heading and the number of the paragraph in that section to identify where your quote came from. In this example, there is only one paragraph under the specific heading, so no paragraph number is needed.

(Remember ALL citations are formatted in APA 7th edition)

Cite a Web Page With No Author

How do you reference a web page that lists no author?

From the  APA Style Blog .

When there is no author for a web page, the title moves to the first position of the reference entry like this:

All 33 Chile miners freed in flawless rescue. (2010, October 13). MSNBC.  Retrieved from http://www.msnbc.msn.com/-id/39625809/ns/world_news-americas/

Cite in text the first few words of the reference list entry (usually the title) and the year. Use double quotation marks around the title or abbreviated title.: ("All 33 Chile Miners," 2010).

Note:  Articles found on the web, like the example above, are not italicized in the reference entry and are not italicized but enclosed in quotations in the in-text citation, just like a newspaper or magazine article.

How to Cite a Website

Last Updated: February 9, 2023 Fact Checked

This article was co-authored by Michelle Golden, PhD and by wikiHow staff writer, Jennifer Mueller, JD . Michelle Golden is an English teacher in Athens, Georgia. She received her MA in Language Arts Teacher Education in 2008 and received her PhD in English from Georgia State University in 2015. There are 7 references cited in this article, which can be found at the bottom of the page. This article has been fact-checked, ensuring the accuracy of any cited facts and confirming the authority of its sources. This article has been viewed 3,561,314 times.

If you're writing a research paper, you'll likely do quite a bit of research online. If you have websites that you want to use as sources for your paper, an entry for the website must appear in the reference list (also called the bibliography or Works Cited) at the end of your paper. You'll also include a citation in-text at the end of any sentence in which you've paraphrased or quoted information that appeared on that website. While the information you need to provide is generally the same across all methods, the way you format that information may vary depending on whether you're using the Modern Language Association (MLA), American Psychological Association (APA), or Chicago style of citation.

Sample Citation Templates

• Example: Claymore, Crystal.
• If no individual author is listed, but the website is produced by a government agency, organization, or business, use that name as the author. For example, if you're using a CDC web page as a source, you would list the author as "Centers for Disease Control and Prevention."

Tip: For your entire Works Cited entry, if an element doesn't exist or isn't provided, simply skip that part of the citation and move on to the next part.

• Example: Claymore, Crystal. "Best-Kept Secrets for Amazing Cupcake Frosting."

• Example: Claymore, Crystal. "Best-Kept Secrets for Amazing Cupcake Frosting." Crystal's Cupcakes , 24 Sept. 2018,

• Example: Claymore, Crystal. "Best-Kept Secrets for Amazing Cupcake Frosting." Crystal's Cupcakes , 24 Sept. 2018, www.crystalscupcakes.com/amazing-frosting.

• Example: Claymore, Crystal. "Best-Kept Secrets for Amazing Cupcake Frosting." Crystal's Cupcakes , www.crystalscupcakes.com/amazing-frosting. Accessed 14 Feb. 2019.

MLA Works Cited Format:

Author Last Name, First Name. "Title of Web Page in Title Case." Name of Website , Day Month Year of publication, URL. Accessed Day Month Year.

• For example, you might write: "The best cupcake frosting techniques are often the least intuitive (Claymore)."
• If you include the author's name in your text, there's no need for a parenthetical citation. For example, you might write: "Award-winning baker Crystal Claymore wasn't afraid to give away all her secrets, sharing her favorite frosting techniques on her website."

• Example: Canadian Cancer Society.

• Example: Canadian Cancer Society. (2017).
• If you're citing several pages from the same website that were published in the same year, add a lower-case letter to the end of the year so you can differentiate them in your in-text citations. For example, you might have "2017a" and "2017b."

• Example: Canadian Cancer Society. (2017). Cancer research.
• If the content you're citing is a stand-alone document, the title should be italicized. This will usually be the case if you're citing a PDF document that appears on a website. If you're not sure, use your best judgment in deciding whether to italicize it or not.

• Example: Canadian Cancer Society. (2017). Cancer research. Retrieved from http://www.cancer.ca/en/cancer-information/cancer-101/cancer-research/?region=on

APA Reference List Format:

Author Last Name, A. A. (Year). Title of web page in sentence case. Retrieved from URL

• For example, you might write: "Clinical trials are used to test new cancer treatments (Canadian Cancer Society, 2017)."
• If you include the author's name in your text, place the year in parentheses immediately after the author's name. For example, you might write: "The Canadian Cancer Society (2017) noted that Canada is a global leader in clinical trials of cancer treatments."

• Example: UN Women.

• Example: UN Women. "Commission on the Status of Women."

• Example: UN Women. "Commission on the Status of Women." UN Women .

• Example: UN Women. "Commission on the Status of Women." UN Women . Accessed February 14, 2019.

• Example: UN Women. "Commission on the Status of Women." UN Women . Accessed February 14, 2019. http://www.unwomen.org/en/csw.

Chicago Bibliography Format:

Author Last Name, First Name. "Title of Web Page in Title Case." Name of Website or Publishing Organization . Accessed Month Day, Year. URL.

• Example: UN Women, "Commission on the Status of Women," UN Women , accessed February 14, 2019, http://www.unwomen.org/en/csw.

About This Article

To cite a website in text using MLA formatting, include the author's last name in parentheses at the end of the sentence you're using the source in. If there is no author, include the title of the web page instead. If you're using APA formatting, include the author's last name followed by a comma and the year of publication in parentheses at the end of the sentence. If you don't know the author's name, use the name of the web page instead. For more tips from our English co-author, like how to cite a website in Chicago style, scroll down!

Reference a Website in Harvard Style | Templates & Examples

Published on 19 May 2020 by Jack Caulfield . Revised on 7 November 2022.

To reference a website in Harvard style , include the name of the author or organization, the year of publication, the title of the page, the URL, and the date on which you accessed the website.

Different formats are used for other kinds of online source, such as articles, social media posts and multimedia content. You can generate accurate Harvard references for all kinds of sources with our free reference generator:

Table of contents

Online articles, social media posts, images, videos and podcasts, referencing websites with missing information, frequently asked questions about harvard website references.

Blog posts and online newspaper articles are both referenced in the same format: include the title of the article in quotation marks, the name of the blog or newspaper in italics, and the date of publication.

The format for a magazine article is slightly different. Instead of a precise date, include the month, season, or volume and issue number, depending on what the magazine uses to identify its issues.

The URL and access date information are included only when the article is online-exclusive.

Prevent plagiarism, run a free check.

To reference posts from social media platforms like Facebook, Twitter and Instagram, include the username and the platform in square brackets. Write usernames the way they appear on the platform, with the same capitalization and symbols.

If the post has a title, use it (in quotation marks). If the post is untitled, use the text of the post instead. Do not use italics. If the text is long, you can replace some of it with an ellipsis.

Online content is referenced differently if it is in video, audio or image form.

To cite an image found online, such as an artwork, photograph, or infographic, include the image format (e.g. ‘Photograph’, ‘Oil on canvas’) in square brackets.

Online videos, such as those on YouTube, Instagram, Vimeo and Dailymotion, are cited similarly to general web pages. Where a video is uploaded under the name of an individual, write the name in the usual format. Otherwise, write the username of the uploader as it appears on the site.

If you want to locate a specific point in a video in an in-text citation, you can do so using a timestamp.

For a podcast reference, you just need the name of the individual episode, not of the whole series. The word ‘Podcast’ is always included in square brackets. As with videos, you can use a timestamp to locate a specific point in the in-text citation.

Online sources are often missing information you would usually need for a citation: author, title or date. Here’s what to do when these details are not available.

When a website doesn’t list a specific individual author, you can usually find a corporate author to list instead. This is the organisation responsible for the source:

In cases where there’s no suitable corporate author (such as online dictionaries or Wikis), use the title of the source in the author position instead:

In Harvard style, when a source doesn’t list a specific date of publication, replace it with the words ‘no date’ in both the in-text citation and the reference list. You should still include an access date:

It’s important to assess the reliability of information found online. Look for sources from established publications and institutions with expertise (e.g. peer-reviewed journals and government agencies).

The CRAAP test (currency, relevance, authority, accuracy, purpose) can aid you in assessing sources, as can our list of credible sources . You should generally avoid citing websites like Wikipedia that can be edited by anyone – instead, look for the original source of the information in the “References” section.

You can generally omit page numbers in your in-text citations of online sources which don’t have them. But when you quote or paraphrase a specific passage from a particularly long online source, it’s useful to find an alternate location marker.

For text-based sources, you can use paragraph numbers (e.g. ‘para. 4’) or headings (e.g. ‘under “Methodology”’). With video or audio sources, use a timestamp (e.g. ‘10:15’).

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

A Harvard in-text citation should appear in brackets every time you quote, paraphrase, or refer to information from a source.

The citation can appear immediately after the quotation or paraphrase, or at the end of the sentence. If you’re quoting, place the citation outside of the quotation marks but before any other punctuation like a comma or full stop.

To cite your sources in an essay in MLA style, you need to have basic information including the author’s name(s), chapter title, book title, editor(s), publication year, publisher, and page numbers. The templates for in-text citations and a works-cited-list entry for essay sources and some examples are given below:

In-text citation template and example:

For citations in prose, use the first name and surname of the author on the first occurrence. For subsequent citations, use only the surname(s). In parenthetical citations, always use only the surname of the author(s).

Citation in prose:

First mention: Annette Wheeler Cafarelli

Subsequent occurrences: Wheeler Cafarelli

Parenthetical:

….(Wheeler Cafarelli).

Works-cited-list entry template and example:

The title of the chapter is enclosed in double quotation marks and uses title case. The book or collection title is given in italics and uses title case.

For sources with two authors, use both full author names in prose (e.g., Mary Strine and Beth Radick).

For sources with three or more authors, use the first name and surname of the first author followed by “and others” or “and colleagues” (e.g., Mary Strine and others). In subsequent citations, use only the surname of the first author followed by “and others” or “and colleagues” (e.g., Strine and others).

In parenthetical citations, use only the author’s surname. For sources with two authors, use two surnames (e.g., Strine and Radick). For sources with three or more author names, use the first author’s surname followed by “et al.”

Quick guide to Harvard referencing (Cite Them Right)

• Site Accessibility: Library Services

Print this page

There are different versions of the Harvard referencing style. This guide is a quick introduction to the commonly-used Cite Them Right version. You will find further guidance available through the OU Library on the Cite Them Right Database .

For help and support with referencing and the full Cite Them Right guide, have a look at the Library’s page on referencing and plagiarism . If you need guidance referencing OU module material you can check out which sections of Cite Them Right are recommended when referencing physical and online module material .

This guide does not apply to OU Law undergraduate students . If you are studying a module beginning with W1xx, W2xx or W3xx, you should refer to the Quick guide to Cite Them Right referencing for Law modules .

Table of contents

In-text citations and full references.

• Secondary referencing
• Page numbers
• Citing multiple sources published in the same year by the same author

Full reference examples

Referencing consists of two elements:

• in-text citations, which are inserted in the body of your text and are included in the word count. An in-text citation gives the author(s) and publication date of a source you are referring to. If the publication date is not given, the phrase 'no date' is used instead of a date. If using direct quotations or you refer to a specific section in the source you also need the page number/s if available, or paragraph number for web pages.
• full references, which are given in alphabetical order in reference list at the end of your work and are not included in the word count. Full references give full bibliographical information for all the sources you have referred to in the body of your text.

To see a reference list and intext citations check out this example assignment on Cite Them Right .

Difference between reference list and bibliography

a reference list only includes sources you have referred to in the body of your text

a bibliography includes sources you have referred to in the body of your text AND sources that were part of your background reading that you did not use in your assignment

Back to top

Examples of in-text citations

You need to include an in-text citation wherever you quote or paraphrase from a source. An in-text citation consists of the last name of the author(s), the year of publication, and a page number if relevant. There are a number of ways of incorporating in-text citations into your work - some examples are provided below. Alternatively you can see examples of setting out in-text citations in Cite Them Right .

Note: When referencing a chapter of an edited book, your in-text citation should give the author(s) of the chapter.

Online module materials

(Includes written online module activities, audio-visual material such as online tutorials, recordings or videos).

FACT SHEET: President   Biden Takes Action to Protect American Workers and Businesses from China’s Unfair Trade   Practices

President Biden’s economic plan is supporting investments and creating good jobs in key sectors that are vital for America’s economic future and national security. China’s unfair trade practices concerning technology transfer, intellectual property, and innovation are threatening American businesses and workers. China is also flooding global markets with artificially low-priced exports. In response to China’s unfair trade practices and to counteract the resulting harms, today, President Biden is directing his Trade Representative to increase tariffs under Section 301 of the Trade Act of 1974 on $18 billion of imports from China to protect American workers and businesses.   The Biden-Harris Administration’s Investing in America agenda has already catalyzed more than $860 billion in business investments through smart, public incentives in industries of the future like electric vehicles (EVs), clean energy, and semiconductors. With support from the Bipartisan Infrastructure Law, CHIPS and Science Act, and Inflation Reduction Act, these investments are creating new American jobs in manufacturing and clean energy and helping communities that have been left behind make a comeback.   As President Biden says, American workers and businesses can outcompete anyone—as long as they have fair competition. But for too long, China’s government has used unfair, non-market practices. China’s forced technology transfers and intellectual property theft have contributed to its control of 70, 80, and even 90 percent of global production for the critical inputs necessary for our technologies, infrastructure, energy, and health care—creating unacceptable risks to America’s supply chains and economic security. Furthermore, these same non-market policies and practices contribute to China’s growing overcapacity and export surges that threaten to significantly harm American workers, businesses, and communities.   Today’s actions to counter China’s unfair trade practices are carefully targeted at strategic sectors—the same sectors where the United States is making historic investments under President Biden to create and sustain good-paying jobs—unlike recent proposals by Congressional Republicans that would threaten jobs and raise costs across the board. The previous administration’s trade deal with China  failed  to increase American exports or boost American manufacturing as it had promised. Under President Biden’s Investing in America agenda, nearly 800,000 manufacturing jobs have been created and new factory construction has doubled after both fell under the previous administration, and the trade deficit with China is the lowest in a decade—lower than any year under the last administration.   We will continue to work with our partners around the world to strengthen cooperation to address shared concerns about China’s unfair practices—rather than undermining our alliances or applying indiscriminate 10 percent tariffs that raise prices on all imports from all countries, regardless whether they are engaged in unfair trade. The Biden-Harris Administration recognizes the benefits for our workers and businesses from strong alliances and a rules-based international trade system based on fair competition.   Following an in-depth review by the United States Trade Representative, President Biden is taking action to protect American workers and American companies from China’s unfair trade practices. To encourage China to eliminate its unfair trade practices regarding technology transfer, intellectual property, and innovation, the President is directing increases in tariffs across strategic sectors such as steel and aluminum, semiconductors, electric vehicles, batteries, critical minerals, solar cells, ship-to-shore cranes, and medical products.   Steel and Aluminum   The tariff rate on certain steel and aluminum products under Section 301 will increase from 0–7.5% to 25% in 2024.   Steel is a vital sector for the American economy, and American companies are leading the future of clean steel. Recently, the Biden-Harris Administration announced $6 billion for 33 clean manufacturing projects including for steel and aluminum, including the first new primary aluminum smelter in four decades, made possible by the Bipartisan Infrastructure Law and the Inflation Reduction Act. These investments will make the United States one of the first nations in the world to convert clean hydrogen into clean steel, bolstering the U.S. steel industry’s competitiveness as the world’s cleanest major steel producer.   American workers continue to face unfair competition from China’s non-market overcapacity in steel and aluminum, which are among the world’s most carbon intensive. China’s policies and subsidies for their domestic steel and aluminum industries mean high-quality, low-emissions U.S. products are undercut by artificially low-priced Chinese alternatives produced with higher emissions. Today’s actions will shield the U.S. steel and aluminum industries from China’s unfair trade practices.   Semiconductors   The tariff rate on semiconductors will increase from 25% to 50% by 2025.   China’s policies in the legacy semiconductor sector have led to growing market share and rapid capacity expansion that risks driving out investment by market-driven firms. Over the next three to five years, China is expected to account for almost half of all new capacity coming online to manufacture certain legacy semiconductor wafers. During the pandemic, disruptions to the supply chain, including legacy chips, led to price spikes in a wide variety of products, including automobiles, consumer appliances, and medical devices, underscoring the risks of overreliance on a few markets.   Through the CHIPS and Science Act, President Biden is making a nearly $53 billion investment in American semiconductor manufacturing capacity, research, innovation, and workforce. This will help counteract decades of disinvestment and offshoring that has reduced the United States’ capacity to manufacture semiconductors domestically. The CHIPS and Science Act includes $39 billion in direct incentives to build, modernize, and expand semiconductor manufacturing fabrication facilities as well as a 25% investment tax credit for semiconductor companies. Raising the tariff rate on semiconductors is an important initial step to promote the sustainability of these investments.   Electric Vehicles (EVs)   The tariff rate on electric vehicles under Section 301 will increase from 25% to 100% in 2024.   With extensive subsidies and non-market practices leading to substantial risks of overcapacity, China’s exports of EVs grew by 70% from 2022 to 2023—jeopardizing productive investments elsewhere. A 100% tariff rate on EVs will protect American manufacturers from China’s unfair trade practices.   This action advances President Biden’s vision of ensuring the future of the auto industry will be made in America by American workers. As part of the President’s Investing in America agenda, the Administration is incentivizing the development of a robust EV market through business tax credits for manufacturing of batteries and production of critical minerals, consumer tax credits for EV adoption, smart standards, federal investments in EV charging infrastructure, and grants to supply EV and battery manufacturing. The increase in the tariff rate on electric vehicles will protect these investments and jobs from unfairly priced Chinese imports.   Batteries, Battery Components and Parts, and Critical Minerals   The tariff rate on lithium-ion EV batteries will increase from 7.5%% to 25% in 2024, while the tariff rate on lithium-ion non-EV batteries will increase from 7.5% to 25% in 2026. The tariff rate on battery parts will increase from 7.5% to 25% in 2024.   The tariff rate on natural graphite and permanent magnets will increase from zero to 25% in 2026. The tariff rate for certain other critical minerals will increase from zero to 25% in 2024.   Despite rapid and recent progress in U.S. onshoring, China currently controls over 80 percent of certain segments of the EV battery supply chain, particularly upstream nodes such as critical minerals mining, processing, and refining. Concentration of critical minerals mining and refining capacity in China leaves our supply chains vulnerable and our national security and clean energy goals at risk. In order to improve U.S. and global resiliency in these supply chains, President Biden has invested across the U.S. battery supply chain to build a sufficient domestic industrial base. Through the Bipartisan Infrastructure Law, the Defense Production Act, and the Inflation Reduction Act, the Biden-Harris Administration has invested nearly $20 billion in grants and loans to expand domestic production capacity of advanced batteries and battery materials. The Inflation Reduction Act also contains manufacturing tax credits to incentivize investment in battery and battery material production in the United States. The President has also established the American Battery Materials Initiative, which will mobilize an all-of-government approach to secure a dependable, robust supply chain for batteries and their inputs.   Solar Cells   The tariff rate on solar cells (whether or not assembled into modules) will increase from 25% to 50% in 2024.   The tariff increase will protect against China’s policy-driven overcapacity that depresses prices and inhibits the development of solar capacity outside of China. China has used unfair practices to dominate upwards of 80 to 90% of certain parts of the global solar supply chain, and is trying to maintain that status quo. Chinese policies and nonmarket practices are flooding global markets with artificially cheap solar modules and panels, undermining investment in solar manufacturing outside of China.   The Biden-Harris Administration has made historic investments in the U.S. solar supply chain, building on early U.S. government-enabled research and development that helped create solar cell technologies. The Inflation Reduction Act provides supply-side tax incentives for solar components, including polysilicon, wafers, cells, modules, and backsheet material, as well as tax credits and grant and loan programs supporting deployment of utility-scale and residential solar energy projects. As a result of President Biden’s Investing in America agenda, solar manufacturers have already announced nearly $17 billion in planned investment under his Administration—an 8-fold increase in U.S. manufacturing capacity, enough to supply panels for millions of homes each year by 2030.   Ship-to-Shore Cranes   The tariff rate on ship-to-shore cranes will increase from 0% to 25% in 2024.   The Administration continues to deliver for the American people by rebuilding the United States’ industrial capacity to produce port cranes with trusted partners. A 25% tariff rate on ship-to-shore cranes will help protect U.S. manufacturers from China’s unfair trade practices that have led to excessive concentration in the market. Port cranes are essential pieces of infrastructure that enable the continuous movement and flow of critical goods to, from, and within the United States, and the Administration is taking action to mitigate risks that could disrupt American supply chains. This action also builds off of ongoing work to invest in U.S. port infrastructure through the President’s Investing in America Agenda. This port security initiative includes bringing port crane manufacturing capabilities back to the United States to support U.S. supply chain security and encourages ports across the country and around the world to use trusted vendors when sourcing cranes or other heavy equipment.   Medical Products   The tariff rates on syringes and needles will increase from 0% to 50% in 2024. For certain personal protective equipment (PPE), including certain respirators and face masks, the tariff rates will increase from 0–7.5% to 25% in 2024. Tariffs on rubber medical and surgical gloves will increase from 7.5% to 25% in 2026.   These tariff rate increases will help support and sustain a strong domestic industrial base for medical supplies that were essential to the COVID-19 pandemic response, and continue to be used daily in every hospital across the country to deliver essential care. The federal government and the private sector have made substantial investments to build domestic manufacturing for these and other medical products to ensure American health care workers and patients have access to critical medical products when they need them. American businesses are now struggling to compete with underpriced Chinese-made supplies dumped on the market, sometimes of such poor quality that they may raise safety concerns for health care workers and patients.   Today’s announcement reflects President Biden’s commitment to always have the back of American workers. When faced with anticompetitive, unfair practices from abroad, the President will deploy any and all tools necessary to protect American workers and industry.

The introduction of AlphaFold 2 1 has spurred a revolution in modelling the structure of proteins and their interactions, enabling a huge range of applications in protein modelling and design 2–6 . In this paper, we describe our AlphaFold 3 model with a substantially updated diffusion-based architecture, which is capable of joint structure prediction of complexes including proteins, nucleic acids, small molecules, ions, and modified residues. The new AlphaFold model demonstrates significantly improved accuracy over many previous specialised tools: far greater accuracy on protein-ligand interactions than state of the art docking tools, much higher accuracy on protein-nucleic acid interactions than nucleic-acid-specific predictors, and significantly higher antibody-antigen prediction accuracy than AlphaFold-Multimer v2.3 7,8 . Together these results show that high accuracy modelling across biomolecular space is possible within a single unified deep learning framework.
