I think there IS a space for Facebook and libraries IF you go about it the right way.
Exhibit A. Library FB Groups and Pages that work:
- Central Library, Cambridge
- People for a Library-themed Ben & Jerry's Flavor
- Jerwood Library, Trinity Hall
- English Faculty Library
What you shouldn't do is use your FB page for your serious and/or extensive announcements. There are other and better ways for exchanging this kind of information.
Exhibit B: Library FB Groups and Pages that don't work (yet!):
I'm not saying a FB page is for every library. It's not even for life. But, if you can make it work and have the time to make it work, it can become a great space for your readers and staff to interact. However,if it's not working, forget about it. Just beacuse 'everyone is on Facebook' doesn't mean you have to be too.
