CMMC incorporates CommSearch (formerly produced by the National Communication Association) and Mass Media Articles Index (formerly produced by Penn State) along with numerous other journals to create a research and reference resource of unprecedented scope and depth in the communication and mass media fields.

ProQuest's Entertainment Industry Magazine Archive is an archival research resource containing the essential primary sources for studying the history of the film and entertainment industries, from the era of vaudeville and silent movies through to 2000. The core US and UK trade magazines covering film, music, broadcasting and theater are all included, together with film fan magazines and music press titles. The magazines have been scanned cover-to-cover in high-resolution color, with granular indexing of all articles, covers, ads and reviews. Trade papers have long been recognized as potentially the single most valuable research material for scholars of the film and media industries. This database includes several trade magazines which have effectively provided the main historical record for their subject areas throughout the 20th century, such as Variety (1905-2000), Billboard (1894-2000), Broadcasting (1931-2000) and The Stage (1880-2000).

Film & Television Literature Index is a comprehensive bibliographic database covering the entire spectrum of television and film writing, including theory, preservation and restoration; writing, production, cinematography; production and film and television reviews.

Publications include Film Journal International, Journal of British Cinema & Television, Film Criticism, Post Script, Variety, and more as well as technical publications such as SMPTE. Mirroring the international film & television industries and cultures, FTLI also includes publications such as Cahiers du Cinema, Filmihullu, SegnoCinema, and Kinetoscopio.
