MathSciNet is a search tool maintained by the American Mathematical Society. The database is different from the other search tools above in that is has, among other features: author profiles, its own mathematics 'subject classification' system (MSC2010), and thousands of reviews of current published materials written by knowedgeable experts. Searches in other databases such as Inspec and Scopus will generally not be as targeted, but may include more cross-disciplinary content.
Google Scholar will largely overlap in content with all of the above subject databases. It is especially good if you need to search for a phrase or sentence, or to look up authors or citations. For off-campus searches, go through the library web site (under Databases) or through this guide.
Google Scholar includes the full-text of articles that have either been 'purchased' by the library or posted to Google 'free' by permission of an author.
Sometimes a Scholar search will turn up citation information only, and no full-text. Citations can be used to search our catalogue for a print copy, or request articles through a 'RACER' loan.
If unsure about the appropriateness of an article, you should consider: the credentials of the authors; whether the writing is coherent; and if bias and error are properly accounted for. Answering these questions will help develop your analytical skills which will in turn make you a more successful writer.
