"The savvy investigator begins his or her search of the literature by contacting --in person (ideally), by phone, by e-mail, or on the Web-the nearest health sciences librarian (or information professional)." Schuster, D. P. P. W. J., & Md (2005). Translational and experimental clinical research (chapter 2 by Christina Sullivan and Neville Prendergast)
All research to some extent relies on the results of previous research endeavors and scientific inquiry. The record of these results in biomedical research is best found in the published health sciences literature. A search of this literature, therefore, should be an integral part of any research undertaking.
