PubMed is a database providing abstracts to articles in medicine, nursing, dentistry, veterinary medicine, allied health, and the pre-clinical sciences; it also indexes articles from the Index to Dental Literature and the International Nursing Index. PubMed is a service of the US National Library of Medicine and includes millions of citations from health and life sciences journals from the present back to the 1950s. PubMed, when accessed by registered Academic users via The TMC Library, links the user to the full text of thousands of articles in subscribed journals. For all who access it, PubMed also links to thousands of open-access articles, either directly via publisher sites or via its PubMed Central repository.
The Cochrane Library is a collection of six databases that contain different types of independent evidence to inform healthcare decision-making including Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register, Database of Abstracts of Reviews of Effects, Health Technology Assessment Database and NHS Economic Evaluation Database
Sources of information in many diverse disciplines are retrievable with Google Scholar. A search can return citations to articles, theses, books, patents, abstracts and court opinions from academic publishers, professional societies, online repositories, universities and the Web itself. Scholar ranks your search results according to the full text of each document, its place of publication, its author, and the frequency/currency of its citation by others. With an individual Google Scholar registration one can set persistent preferences, among them the convenient option to display TMC Library's holdings at title level (and/or those of other libraries.) In either case, the "Advanced Scholar Search" page allows restriction of your search results to a particular date range, subject area, author or journal.
