Here is a guide that walks you through some features of PsycINFO, such as how to search, the structure of records, etc.
Academic Search CompleteA good starting point for any research, Academic Search Premier provides access to peer-reviewed articles across multiple subjects, including full-text access for many articles.
A version of Google that searches through academic resources. If you are on campus, you may be able to obtain full-text articles through a Google Scholar search.
Social Sciences Citation IndexSimilar to PsycINFO, Social Sciences Citation Index contains a collection of abstracts and citations to help you find the research that is relevant to your topic. If possible, it also provides full-text access to the article.
