MLA features some of the best retrospective coverage among databases in the social sciences and humanities, indexing a wide range of materials as far back as 1926. Over 1.8 million citations to journal articles, books, and dissertations on modern languages, literature, film and folklore are included. In many cases book reviews can also be found. Translations of literary works are not indexed in MLA.

• Indexes materials from over 1,000 book publishers and over 7,000 journals and series, which are listed (and individually searchable) via the MLA Directory of Periodicals.
• Huge number of search options
• Includes a thesaurus
