Wikis

I think the most helpful library wikis are those such as St. Joseph County Public Library's Subject Guides--they provide information that's extremely helpful to patrons in an easy-to-update format. Librarians have to go where the patrons are because more and more patrons are going directly to the computer and bypassing the reference desk. For example, the SJCPL's subject guide topic Biography includes such helps as Biography, Memoir, what's the difference? , as well as links to related topics which include keeping a journal, blogging, photoblogging and scrapbooking.
