Two days ago, Liz and I decided to informally query the online library community and the Kansas library community on what the top five uses were for library computers. We received a lot of responses via social networks and Kansas library listservs. You can read a running list of results over on the NEKLS tech blog.
I then threw the list into the Wordle creator several times, standardizing the list a bit more each time (basically just grouping similar tasks together). Here is the final graphic. You can clearly see what the top five uses for computers are!
Heather Braum is the Technology Librarian at NEKLS. She can be reached by phone, by email (hbraum (at) nekls.org), or through several online chat services (look Heather up by her email address). Visit the

And yeah…what do you need in a netbook…wireless.
All of these activities appear to be web-based.
