What is a QR code?
A QR ("quick response") code encodes information such as a URLs, text, or images and can be read by certain mobile phones. QR codes are used for a wide range of things. We use them in the library to link users to movie trailers for some of our DVDs, and to connect people to the online versions of some of our print journals. You can learn more about QR codes by checking out our QR code LibGuide.
