PubMed Tutorial is a "web-based learning program that will show you how to search PubMed, the National Library of Medicine's journal literature search system." Clear, detailed explanations and helpful animations guide users in making the most of PubMed's many features. The level of detail in this tutorial is amazing, yet not overwhelming (thanks again to animations and demonstrations that replicate the PubMed user interface). A final review section offers a number of practice exercises.
