TPL:AR is a free augmented reality app developed by the Toronto Public Library for Android devices. The app uses augmented reality technology to bring library materials to life, allowing users to explore The List, a collection of recommended reads for youth. By scanning the pages of The List with their smartphone, users can access hidden content such as book reviews, images, and videos. Additionally, the app allows users to scan their TPL library card for easy access to search the collection, manage their account, find their local branch, or see a calendar of upcoming events.

It should be noted that some Android devices may experience a few seconds of a black screen before the AR camera opens. This is part of the initialization process, which may vary depending on the phone version. It is also important to note that the library's third-party services are governed by their own privacy policies and practices, not the library's. Users are advised to consult the Terms of Service and Privacy Policies of these services before agreeing to use them.

Overall, TPL:AR is a useful and innovative tool for exploring the library's collection and engaging with library materials in a new and exciting way.
