| Abstract: | Experienced searchers can help their patrons find the "best" by employing any of several techniques which might filter search results. Using a sample search on Alzheimer's Disease, this article describes and illustrates the following five objective indicators which might be considered signs of quality: methodological rigor, document attributes, peer review, journal reputation, and filtering at input. Sample techniques and results are presented for six databases: MEDLINE, CINAHL, EMBASE, SAMM, CCML, and JWAT. Understanding of the patron's need and knowledge of the structure and contents of the database will determine when each should be applied to search results. |
