There are 3 American Psychological Association (APA) databases that will provide you with citations and full-text for authoritative literature on your topic. All three databases use the ProQuest platform:
- PsycINFO provides citations and abstracts to scholarly journal literature. Some full-text is available. Journals from a variety of publishers, both national and international, are indexed here.
- PsycBOOKS provides citations to scholarly books, and the electronic texts of the books are available.
- PsycARTICLES provides full-text access to scholarly journal literature published by the American Psychological Association. While everything here is full-text, it incudes fewer journals (yet those journals are of high quality).
If you wish, you can search all 3 at the same time.
