QR codes and augmented reality offer opportunities for academic libraries. QR codes allow libraries to provide mobile access to information by encoding URLs, text, or data into scannable barcodes. Libraries are using QR codes in print and online in various ways, such as for research guides, room reservations, exhibitions, and catalog records. Augmented reality overlays virtual information onto the real world through mobile apps. While still early, augmented reality shows promise for creating interactive campus and library tours or leveraging existing information. Both QR codes and augmented reality have potential to engage users in new ways through mobile technologies.
