This iPhone app was created by one the network’s patrons. He created it to make his library life more mobile, and it is available as a free download from the iTunes Store. Unfortunately, it only works with the iPhone and not the iPod Touch.
When I first heard about the app, my first concern was patron privacy, but the creator/owner of the app, guaranteed that he collects no data. The application only communicates with you (the user) and the Minuteman Library Network’s servers.

Unfortunately, no patrons or librarians have made an application for Android or Palm, but, hopefully, one will appear sometime in the near future.
