ACRL has released "Keeping Up With… Augmented Reality."
Here's an excerpt:
At a minimum, libraries will need to be prepared to support augmented reality if and when it becomes more prevalent in textbooks and other print materials. But, while these materials are certainly relevant to the work of academic libraries, there are also several interesting library-specific augmented reality tools in use at various institutions. ShelvAR, developed by the Miami University Library, is an excellent example of how augmented reality can increase the efficiency of libraries' existing workflows. Available for use with any iOS or Android device with a camera, this app can scan any tagged library materials and overlay a red X over any item that is out of place on the shelf.
