Use research databases that index, describe, and add subject terms to articles-- all of which makes it easier to find relevant material. Use the links labeled Find Full Text in the record to find the article through other library sources.
The primary databases for Psychology are:
Web of Science and Social Sciences Citation Index - Best tools for finding articles in scholarly journals that scholars refer to most. The sources are all selected on the basis of their impact on scholarly publishing, so you can be confident about the quality of the publication. This is an excellent tool for tracking down who has used a paper in their own research. Google Scholar has a similar "cited by" link that leads to a much wider (less selective) set of material. It is interesting to compare results.
Google Scholar is a subset of Google Web Search that searches specifically for scholarly materials such as peer-reviewed papers, theses, books, abstracts and technical reports from broad areas of research. By searching Google Scholar from Temple's library web site through this Google Scholar link , you will automatically have direct access, both on and off campus, to subscription articles already paid for through the library. Just look for the "Find Full-Text @ TU" link within search results.
Keep in mind that Google Scholar uses rankings that will likely bring up highly cited material that may also be quite old to the top of the results. You can use the year range to limit to more current results (labeled "anytime" towards the top of the search results page in Google Scholar and "Date" in Google Advanced.)
PsycINFO (via EBSCOhost | via Ovid) Most comprehensive tool for finding sources in psychology. (EBSCOhost and Ovid are different companies that supply the same content but have different search features.) Contains citations and summaries of journal articles, book chapters, books and technical reports, as well as citations to dissertations. The real strength of these databases for searching is the organization of information about articles into records with searchable fields and the addition of subject terms, for example DE "Post-Traumatic Stress" OR DE "Posttraumatic Stress Disorder"
PILOTS Database (Published International Literature On Traumatic Stress) is an interdisciplinary bibliographical database and includes citations to literature on Post-Traumatic Stress Disorder (PTSD) without disciplinary, linguistic, or geographical limitations. The database includes citations and abstracts to journal articles, books, book chapters, dissertations, and government documents.
