The ACL Anthology is run by the Association for Computational Linguistics (ACL) and hosts papers from official ACL venues as well as other organizations. Its homepage describes it as "a library of publications in the scientific fields of computational linguistics and speech and natural language processing," and the site reports a span of 75 years, which places its earliest indexed material in the mid-20th century. It is best understood as the field's central open bibliography rather than a publisher or a peer-review body: the papers come from conferences and journals, and the Anthology organizes and serves them.

Who runs it

• Operator: the Association for Computational Linguistics (ACL), the main professional society for computational linguistics and NLP.
• Scope of hosting: papers from "official venues of the Association for Computational Linguistics and other organizations," so the catalog is broader than ACL's own conferences.
• Role: it is a library/index. Acceptance decisions belong to the individual venues, not to the Anthology.

What the numbers say

The homepage presents running totals that are useful for judging the Anthology's scale:

These figures are cumulative and change as new proceedings are added, so treat them as a snapshot rather than fixed constants.

History and coverage

The "75 years" figure is the clearest historical signal on the page. Counting back from the current year, that reach extends to roughly the mid-20th century, which is consistent with the Anthology's practice of digitizing and indexing older computational linguistics literature alongside new proceedings.

Coverage is organized by venue, and the year lists under each venue show how far back each one goes. Examples visible on the homepage:

• ACL (Annual Meeting of the Association for Computational Linguistics): year links running from 2026 back to 1979 and earlier.
• COLING (International Conference on Computational Linguistics): links from 2025 back to 1965.
• CL (Computational Linguistics journal): links from 2026 back to the 1970s.
• EACL, EMNLP, AACL, TACL, EAMT, AMTA, DND: each with its own year range, generally starting later than ACL or COLING.

The pattern is that flagship ACL venues have the deepest backfiles, while regional chapters, workshops, and sister conferences appear from their founding onward.

Why it matters in the field

The Anthology functions as the default place to find and cite computational linguistics and NLP papers. Because it aggregates official venue proceedings in one searchable library, it is usually the first stop for locating a paper by title, author, or venue, and for checking what a given conference published in a given year. The site also exposes an Authors index and an "API & data" entry point, which is what makes it usable as infrastructure for literature search and bibliometric work rather than just a reading site.

Practical implications

• If you need a paper from an ACL-family venue, search the Anthology first; it is the canonical index.
• If you are checking whether a venue is "official," look for it in the venue list — the Anthology distinguishes ACL venues from other organizations' venues.
• If you need bulk metadata rather than individual papers, the "API & data" link is the relevant entry point.
• If you are judging historical depth for a venue, use the year links under that venue rather than the site-wide 75-year figure, since individual venues start at different points.

The ACL Anthology (aclanthology.org) is a digital library of publications in computational linguistics and speech and natural language processing. It hosts papers from the official venues of the Association for Computational Linguistics (ACL) and other organizations, and it is the standard place to find and cite NLP research. If you are looking for a paper from an ACL-family conference or journal, this is usually the fastest route to a free, stable copy.

What it covers

The Anthology collects peer-reviewed work from conferences, journals, and workshops in the field. Its own site describes it as hosting papers from ACL's official venues plus other organizations, so coverage extends beyond a single society's events.

Venues listed on the site include:

• Flagship conferences: ACL, EMNLP, NAACL, EACL, AACL, COLING
• Journals: Computational Linguistics (CL), Transactions of the Association for Computational Linguistics (TACL), Dialogue & Discourse (DND)
• Other organizations' venues: AMTA (machine translation), EAMT, and many workshops

The site organizes venues by type (flagship venues, journals, other venues) and by decade, with years listed under each venue so you can jump directly to a specific edition.

How large is it

The homepage reports the following figures:

The 75-year span is why you see venue year lists reaching back to the 1950s and 1960s (for example, COLING entries from 1965 and 1967). This makes the Anthology useful for both current research and historical tracing of a subfield.

What you can do with it

• Find a specific paper by title, author, or venue when you already know what you need.
• Browse a venue's proceedings year by year, for example all ACL 2024 papers or a specific workshop.
• Track a research area over time by scanning the same venue across decades.
• Get citation-ready metadata for papers, since entries are indexed by author and venue.
• Access data programmatically through the site's Authors API & data offering, which is relevant if you want to build a bibliography, analyze publication trends, or bulk-download metadata.

Who maintains it

The Anthology is associated with the Association for Computational Linguistics and is run as a community resource for the field. The site provides a Feedback channel, which is the route to use if you spot a missing paper, a metadata error, or a broken link.

Practical notes

• Access is web-based; the site does not present itself as a paid service, and its purpose is to host and distribute publications.
• Because it aggregates many organizations' venues, not every paper in the field is guaranteed to be there — coverage follows the venues it indexes.
• If you need machine-readable records rather than reading individual papers, start with the API & data option rather than scraping pages.

For a researcher, the practical summary is: use the Anthology as your first stop for ACL-family papers, browse by venue when you want a conference's full proceedings, and use the API when you need the data at scale.

Yes. The ACL Anthology provides an "Authors API & data" entry point, and the site is built as a searchable library of computational linguistics and speech/NLP publications. That makes it usable for both manual literature search and programmatic access to paper and author metadata. The exact endpoints, file formats, and rate limits are not described in the page evidence here, so treat this as a pointer to the official API/data section rather than a full technical specification.

What the ACL Anthology Is

The ACL Anthology is a library of publications in computational linguistics and speech and natural language processing. It hosts papers from official venues of the Association for Computational Linguistics and other organizations.

The scale reported on the site:

This breadth is why the Anthology is commonly used as a source for literature reviews, venue analysis, and author-level bibliometrics.

What "Authors API & data" Implies

The presence of an "Authors API & data" link on the site indicates that author-related information is exposed in a structured, reusable form, not only as rendered web pages. In practice, this kind of access is what you would use for:

• Literature analysis — counting papers per venue, per year, or per author.
• System development — populating a reference manager, building a search tool, or linking papers to external knowledge bases.
• Reproducibility checks — verifying that a cited paper exists and retrieving its canonical metadata.

Because the page evidence does not list specific endpoints or schemas, confirm the current interface on the site's API & data page before writing code against it.

How to Get Started

1. Open the ACL Anthology homepage at aclanthology.org.
2. Locate the "Authors API & data" link in the site navigation.
3. Read the documentation there for the available endpoints, data files, and any usage conditions.
4. Test with a small query first — for example, retrieve metadata for one known paper or author — before scaling up.
5. Verify the returned fields (title, authors, venue, year, identifiers) match what you need for your task.

Expected result: you obtain structured records you can store, filter, or join with other datasets, instead of scraping rendered HTML.

Venues You Can Expect to Cover

The Anthology organizes content by venue, and the site lists both flagship and other venues. Examples visible on the page include:

• ACL — Annual Meeting of the Association for Computational Linguistics
• EMNLP — Conference on Empirical Methods in Natural Language Processing
• EACL — European Chapter of the ACL
• AACL — Asian Chapter of the ACL
• COLING — International Conference on Computational Linguistics
• TACL — Transactions of the Association for Computational Linguistics
• CL — Computational Linguistics
• AMTA — Conference of the Association for Machine Translation in the Americas
• EAMT — Conference of the European Association for Machine Translation
• DND — Dialogue & Discourse
• Findings

If your project depends on a specific venue or year range, check that it appears in the venue list before assuming full coverage.

Practical Caveats

• No pricing or login details are stated in the available evidence. Do not assume the API or data files are unrestricted; check the official page for terms.
• Coverage is not the same as completeness. A venue may have gaps in older years even though the overall archive spans 75 years.
• Metadata quality varies by source. Older entries may have less consistent author or affiliation data than recent ones.
• Plan for rate limits and caching. Even a public API benefits from local caching if you are making repeated queries.

When This Is the Right Resource

Use the ACL Anthology's API and data access if you need publication and author metadata from ACL-affiliated and related NLP venues, and you want a citable, canonical source rather than a general web scrape. If you need full-text mining at scale, verify separately whether the data access covers text or only metadata.

The ACL Anthology (aclanthology.org) is a free-to-access library of publications in computational linguistics and speech and natural language processing. It hosts papers from official venues of the Association for Computational Linguistics and other organizations, and as of the site's own statistics it contains 131,151 papers, 134,285 authors, 3,500 volumes, and 534 venues spanning 75 years. You can find a paper in two main ways: type keywords into the search box, or browse by venue and year. Both paths lead to the same paper pages, so pick whichever matches what you already know.

Searching by keyword

Use the search box when you know the topic, title fragment, or author name but not the venue.

1. Enter your terms in the search field on the homepage.
2. Submit the query. The page reports a result count (shown as "Search results · 0" when nothing matches) and lists matching papers.
3. Open a result to reach its paper page, where you can read the abstract and access the PDF.

The homepage also shows a "Recently updated · 0" counter, which reflects items added or revised recently — useful if you are tracking new additions rather than searching a fixed topic.

Expected result: a filtered list of papers plus a count. If the count is 0, broaden the terms or switch to browsing by venue, since search only matches what is indexed.

Browsing by venue

If you know the conference or journal, browsing is more reliable than keyword search. The Anthology organizes content under venues, and the homepage groups them into sections such as "ACL venues," "Flagship venues," and others.

Each venue entry lists its available years as links. For example:

• ACL (Annual Meeting of the Association for Computational Linguistics) — years from 1979 through 2026
• EMNLP (Conference on Empirical Methods in Natural Language Processing) — 1996 through 2025
• EACL (European Chapter of the ACL) — 1983 through 2026
• NAACL and AACL (regional chapters) — listed with their own year ranges
• COLING (International Conference on Computational Linguistics) — 1965 through 2025
• TACL (Transactions of the ACL) — 2013 through 2026
• CL (Computational Linguistics journal) — 1974 through 2026
• AMTA, EAMT, DND (Dialogue & Discourse), and others

Clicking a year takes you to that volume's table of contents, where papers are listed individually.

Filtering by decade

The venue pages let you narrow a long year list by decade. The available filters are:

• All years
• 2020s, 2010s, 2000s, 1990s, 1980s, 1970s, 1960s, 1950s

This matters for long-running venues. ACL, for instance, spans 1979 to 2026, so selecting "2020s" removes decades of older entries and shortens the page to recent meetings. Use it when you want current work; skip it when you are tracing the history of a topic.

Choosing between search and browse

Other entry points

The homepage also exposes an Authors section and an API & data link. The API is the practical route if you need to query the collection programmatically or build your own index rather than click through pages. A Feedback link is provided for reporting issues with the site or its records.

Common snags

• Zero results: the count is displayed explicitly, so a 0 tells you the terms did not match — not that the paper is absent from the field. Try alternate spellings or the venue route.
• Venue name ambiguity: many venues share acronyms across organizations. Check the full name shown next to the acronym before assuming you are in the right place.
• Year gaps: listed years are not always consecutive (for example, EACL shows 1983, 1985, 1987, 1989, 1991, 1993, 1995, 1997, 1999, then 2003, 2006, 2009, 2012, 2014, 2017, 2021, 2023, 2024, 2026). A missing year usually means no proceedings were published or indexed for it, not that the page is broken.
• Recency: the "Recently updated" counter is small by design; it tracks recent changes, so do not treat it as a full new-arrivals feed.

The ACL Anthology hosts papers from the official venues of the Association for Computational Linguistics (ACL) and other organizations, covering computational linguistics, speech, and natural language processing. According to the site, it currently contains 131,151 papers, 134,285 authors, 3,500 volumes, and 534 venues spanning 75 years. That means it is not limited to a single conference — it aggregates a broad set of conferences, journals, and workshops, so you can usually check whether a specific venue is covered before searching for a paper.

Flagship ACL conferences

These are the main annual meetings run by ACL and its chapters, and they appear with long backfiles:

• ACL – Annual Meeting of the Association for Computational Linguistics (listed from 1979 onward)
• EMNLP – Conference on Empirical Methods in Natural Language Processing (listed from 1996 onward)
• NAACL – North American Chapter of the ACL (referenced among flagship venues)
• AACL – Asian Chapter of the ACL (2020, 2022, 2023, 2025)
• EACL – European Chapter of the ACL (1983 onward)

Other conferences and workshops

Beyond the flagship meetings, the Anthology indexes related conferences and co-located events:

• COLING – International Conference on Computational Linguistics (1965 onward)
• AMTA – Conference of the Association for Machine Translation in the Americas (1994 onward)
• EAMT – Conference of the European Association for Machine Translation (1993 onward)
• Plus numerous workshops and Findings volumes associated with the main conferences

Journals

The Anthology also hosts journal publications, including:

• Computational Linguistics (CL) – listed from 1974 onward
• TACL – Transactions of the Association for Computational Linguistics (2013 onward)
• Dialogue & Discourse (DND) – listed from 2010 onward

How to check coverage

1. Go to aclanthology.org.
2. Browse the venue list on the homepage, which groups entries by type (flagship venues, other conferences, journals).
3. Use the year links under each venue to confirm whether a specific year is included.
4. If you need programmatic access, the site offers an Authors API and data downloads.

Because the Anthology is a library rather than a single conference site, the practical answer is: if your target venue is an ACL venue or a closely related NLP/CL conference or journal, it is likely included. For anything outside that scope, check the venue list directly before assuming coverage.
