Libraries are exploring the use of Quick Response (QR) codes, to market to and connect users with libraries' services. The University of the Pacific has been experimenting with QR codes in an innovative way: to introduce first-year music majors to the physical music library materials via a QR code scavenger hunt. This article discusses the library literature on QR codes and scavenger hunts, as well as the University of the Pacific's QR code scavenger hunt from creation to assessment. Additionally, recommendations are given for designing a similar pedagogical tool at your library.
