Social Media and Public Libraries

I was interested in Public Libraries News on the use of social media to promote public libraries.  This was probably an area of the Libraries Transformation Project where we did not devote as much attention as we ought to have done, but is being developed.  However, it primarily looks at the Internet as a way of promoting library services, I would argue that it is (or could be) a part of the library service.  If you go to the existing Brent library service pages, you can do quite a lot of stuff you could traditionally only do in the library itself.  You can look up items in a catalogue, renew them, borrow ebooks, check your account, find out about events, reserve items, book a computer and find out about services in general.  I expect that over time it will develop more to allow you to network with other library users, say to rate and review books, or to discuss them.
