Nickerson's thoughts Thing #23

I googled web 2.0 23 things and came up with The Public Library of Charlotte and Mecklenberg, it appears that ehy not only had 23 things but they had 43 things in total. I think that it is alot of information but as a teacher you need to know when you can use something from the internet, book or a magazine and when you need to get permission or how long you can use it.
