Communication & Mass Media Complete provides the most robust, quality research solution in areas related to communication and mass media. CMMC incorporates the content of CommSearch (formerly produced by the National Communication Association) and Mass Media Articles Index (formerly produced by Penn State) along with numerous other journals in communication, mass media, and other closely-related fields of study to create a research and reference resource of unprecedented scope and depth encompassing the breadth of the communication discipline. CMMC offers cover-to-cover (“core”) indexing and abstracts for more than 570 journals, and selected (“priority”) coverage of nearly 200 more, for a combined coverage of more than 770 titles. Furthermore, this database includes full text for over 450 journals. Many major journals have indexing, abstracts, PDFs and searchable cited references from their first issues to the present (dating as far back as 1915). CMMC contains a sophisticated Communication Thesaurus and comprehensive reference browsing (i.e. searchable cited references for peer-reviewed journals covered as “core”). In addition, CMMC features over 5,400 Author Profiles, providing biographical data and bibliographic information, and covering the most prolific, most cited, and most frequently searched for authors in the database. To further develop and enhance this database, EBSCO has established two working groups of expert advisors represented by leading librarians, bibliographers, and professionals in the areas of communication and mass media.
