How do I link to publications in the ACL Anthology?

Every paper in the Anthology is assigned an Anthology ID. After 2020, identifiers are of the form {year}.{venue}-{volume}.{#}, where {year} is the four-digit year, {venue} a lowercased venue code comprising ASCII letters and digits, {volume} is a volume name or number, and {#} is the paper number. Prior to 2020, this identifier took the form CYY-VPPP or CYY-VVPP, where C is a collection, YY a two-digit year, V a volume, and P a paper ID. The canonical URL of an Anthology paper is given by appending this identifier to the Anthology’s base URL https://www.aclanthology.org/; e.g., https://www.aclanthology.org/2020.iwclul-1.4 (new style) or https://www.aclanthology.org/E91-1001 (old style). This is the paper’s landing page, which includes (among other things) a link to the PDF.

Many papers in the Anthology also have Digital Object Identifiers (DOIs). Both the DOIs and the canonical Anthology URLs embed the 8-character ACL Anthology Identifier. When available, DOI URLs will redirect to the Anthology canonical URL, and will be listed on that page.

Variations of the canonical URL can be used to access the PDF and citation format files directly:

and so on.
