Communication Studies research can be found in the databases Communication & Mass Media Complete and Communication Abstracts.
If you know you need an article from a specific journal, try searching for the journal title using ALICE. ALICE tells you where to find the full text of a journal we subscribe to, which may be in these databases, or may be elsewhere, like a publisher website.
If you're not finding the articles you need take a look at my search suggestions, or get it touch with me. We can discuss over email (firstname.lastname@example.org) or in person.
