The MLA International Bibliography is a subject index for books, articles and websites published on modern languages, literatures, folklore, and linguistics. It is produced by the Modern Language Association (MLA), an organization dedicated to the study and teaching of language and literature. The electronic version of the Bibliography dates back to 1925 and contains over 2 million citations from more than 4,400 periodicals (including peer-reviewed e-journals) and 1,000 book publishers. It is compiled by the staff of the MLA Department of Bibliographic Information Services with the cooperation of more than 100 contributing bibliographers in the United States and abroad. Such international coverage is represented by literature from Africa, Asia, Australia, Europe, and North and South America, and while the majority of records are from English-language publications, at least sixty other languages are represented including French, Spanish, German, Russian, Portuguese, Norwegian, and Swedish.

The database also has an identifiable subset of more than 100,000 records that constitute the JSTOR subfile. This consists of citation records for documents in JSTOR's Language and Literature Collection as well as relevant articles from their Asian Studies collection. The documents date back as far as 1881 and contain direct links to the full-text articles on the JSTOR website, available to subscribers of JSTOR.

Subscription to the MLA International Bibliography also includes access to the MLA Directory of Periodicals database. Full text links to Project Muse journal and ProQuest Digital Dissertations are also included in this database.
