Well, this is something I already know! My sons introduced me to Wikipedia and they keep tabs on Penn State football players and do additions and corrections to posts.
I looked at The Book Lovers and the Bull Run Library Wikis. I think we could use one for Reader's Advisory at the branches and I would try one for my Middletown Genies group. Members could share information and everyone would have access.
I created an account and added my blog to the Frederick County list. WooHoo!
