Shelving Made Easy (or Easier)

A computer-science professor is testing a shelf-reading app that can scan an entire shelf’s worth of books and alert workers which ones are out of place. The app he came up with, tentatively called Shelvar, relies on special tags—kind of like QR codes—attached to the books’ spines. Each tag “exactly represents the call number” of each book. A user with a current-generation smartphone or tablet computer scans the shelf using the app, and Shelvar indicates which books aren’t in the right places. Visual cues, including directional arrows, indicate where the misfiled book ought to go.
