The Plymouth Public Library announced the launching of a mobile app that allows users to access library services through smart phones. The app is called “PPL To Go” and it can be downloaded for free and used on iPhones and Android phones. The app can search the library catalog, place holds, and renew books. And if the user sees a book, DVD, or CD in a store, the app can scan the bar code and determine whether the library has the item. To get the app, visit: http://bit.ly/PlymouthApp.
