Getting started with library research in history of medicine
McGill's library catalogues: Classic Catalogue and WorldCat
McGill currently has two library catalogues, its primary catalogue, WorldCat, and a local catalogue containing print books, Classic Catalogue.
Finding books in history of medicine: one way to narrow your search (i.e., to eliminate contemporary medical literature from your results) is by searching the the Osler Library subcatalogue of McGill's Classic Catalogue:
Click the "Sub-catalogues" tab, then click "Osler Library of the History of Medicine" under the Library and Collections category.
Run your search! Note that Classic Catalogue will not retrieve any of McGill's electronic resources.
Use McGill WorldCat to find not just books, but all the library's electronic resources as well as articles.
