Your Research Toolbox (University of Kentucky)
A four module tutorial that includes developing a research strategy, using the library catalog, using periodicals databases, and effectively evaluating information. Each module is a narrated PowerPoint produced into video--the first module includes some humorous video clips as well. The tutorial was created for first year students to learn the basics of using the research library. Needs Windows Media Player & can take a while to download - but worth the wait.
