These are the databases recommended by me and your professor. We do not recommend using other databases, as they may cause your computer to implode.
Just kidding! In all seriousness though, if you want to use other databases, let's have a conversation (contact me, Julie, or your professor).
Communication Source offers abstracts and indexing as well as full-text content from publications worldwide pertaining to Communication, Linguistics, Rhetoric and Discourse, Speech-Language Pathology, Media Studies and other fields relevant to the discipline.
This multi-disciplinary database has records for nearly 18,000 periodicals - journals, magazines, and newspapers - of which nearly 16,000 are peer reviewed. It provides full text for more than 5,000 journals, and you can use Journal Finder to locate articles that do not have a PDF readily available.
