If you’ve ever tried to search for drugs or chemicals in PubMed, you know how difficult it can be. The National Library of Medicine has created a tutorial offering “…tips on effectively and efficiently searching PubMed for drugs and chemicals. Nine brief modules with video demonstrations include guidance on substance-related Medical Subject Headings (MeSH), using the MeSH Database, effective searching with pharmacological action terms, converting special characters in systematic names, and using tags in searching.” This tutorial and many other tutorials, webinars and classes are accessible by clicking the PubMed Tutorials link on the PubMed homepage, as shown below.*
