Think you're a PubMed expert? Do you know about Single Citation Matcher? If not, ask your reference librarian to show you the next best thing to an iPod.
Did you know PubMed doesn't index every scientific or medical journal? Scopus and Web of Science are two other biomedical literature databases that can be useful. They also include meeting abstracts and proceedings, which PubMed does not.
Check with your organization's reference librarian to learn how to access these databases and how to more effectively search them. They also conduct literatures searches, set up research alerts, aid in managing your overload of information, among numerous other services.
