These are my links for February 21st through February 24th:

• BiblioCommons - Billed as a soon-to-be-unveiled "social discovery system for libraries," whatever that means.
• E-LIS - Eprints for LIS - An open archive for papers, presentations, articles, syllabi, and other writings relating to library and information science.
• LibraryFind - Metasearch software. A great example of open source software developed by and for librarians, including folks like Dan Chudnov. I’d love to try it out.
• Blogging believers: Who’s out there in the blogosphere? - A summary of a recent survey of Christian bloggers.
• WorldCat Registry - An interesting new service from WorldCat that provides a way to integrate all kinds of library profile information in one place.
