Figure 1. PubMed home page (www.ncbi.nlm.nih.gov/entrez/query.fcgi). The National Library of Medicine allows unrestricted online access to MEDLINE through PubMed. PubMed has several useful features. These include the 'MeSH Browser', which allows users to identify the optimal Medical Subject Headings relevant to a given clinical topic; 'Clinical Queries,' where a single-click filter based on this strategy is now available; and an option for storing search strings (the 'Cubby' feature).>
