The following databases contain citations and abstracts for published research in the social and biomedical sciences for the last 30 or so years. Search on a keyword, and the database will return a list of journal articles and book chapters that are relevant to that keyword. You can generally find the actual journal articles and book chapters in a well-stocked university library.
The PubMed database includes citations to biomedical journal articles going back to the mid 1960's. Around 4500 journals, covering all aspects of health and medicine, including behavioral health, are indexed for PubMed. Both very simple more complex search strategies can be used to search PubMed. Links are included from the citations to articles that are available full-text online, either free to the public or by subscription. For more information see the PubMed Fact Sheet, http://www.nlm.nih.gov/pubs/factsheets/pubmed.html
The NLM Gateway provides one access point to multiple databases maintained by the National Library of Medicine, including MEDLINE (1966- ), OLDMEDLINE (pre 1966), MEDLINEplus, LOCATORplus, DIRLINE, and others. These databases index various types of health-related materials such as citations to journal articles, books, serials, and audiovisuals, and meeting abstracts. Links to full-text information for health care consumers go to the MEDLINEplus web site. For more information see the NLM Gateway Fact Sheet, http://www.nlm.nih.gov/pubs/factsheets/gateway.html.
The PsychInfo database provides searchable access to published psychological and social sciences literature. Online access to PsychInfo costs money. Anyone can purchase a 24-hour pass to the system for $9.95. Americal Psychological Association members can purchase an annual pass for approximately $50.
