In Fall 2006 on this very blog I bemoaned the fact that Facebook began shutting down library profiles. On Wednesday, Facebook launched Facebook Pages--basically an advertising mechanism that allows organizations, companies, and other entities the ability to create an official presence on Facebook. Nicole and I both immediately saw the opportunity this might create for libraries. Delightfully, Facebook seems to recognize the desire of some librarians to use Facebook as one of the Page categories is "Library/Public Building." How cool.
I created a Facebook group to further discuss the phenomenon and to share Facebook Page urls (you need a Facebook account to view this). Over 40 libraries have created a presence since Thursday morning. This is exciting stuff.
