For those who appreciated our earlier posts on barcode scanning and WorldCat apps, take note of the RedLaser app. Scan a barcode on a book, and RedLaser will use WorldCat data to let you know which nearby libraries have a copy. Remember: if you come across a title Johns Hopkins doesn’t own, Interlibrary Loan can get it for you.

For $0.99 in the iTunes app store, this app combines book barcode searching with services built around electronics, games, housewares, and food. Watch the video below to see the app in action.
