These e-journal collections provide access to many journals in the field of Communications Studies, but they are limited in scope and coverage compared to subject databases. In most cases, it's better to search subject databases to identify articles, and then use the Primo Search to access the materials in these e-journal collections.
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 encompassing the breadth of the communication studies discipline.
In secondary sources, authors analyze and interpret primary source materials.
Secondary sources can be scholarly or popular. Scholarly sources (sometimes called "academic" or "peer-reviewed" sources) are written by and for experts and typically include bibliographies and citations. Popular sources are written for a general, non-expert audience and can be authored by anyone.
