Have you seen LibSite? It's a social networking sie that showcases great library web sites. "Sites" can include content, library home pages, and blogs. I promoted the awesome Danbury Library Catalog.
Check out web sites that librarians (and non-librarians, theoretically) think are cool, such as the Seattle Public Libary, the Library of Congress blog, and, of possible interest to the cogsci readers, the William James Cybrary.
There's only one entry tagged school library; anyone want to add another?!
