QR codes are a type of barcode, that can be used to send a smartphone user to a specific webpage, without the user having to type in a long or difficult URL.
How are QR codes used by the Library?
The QR code attached to a Linköping university library book, and to the detailed item information in the library catalogue, is a web address that leads to the detailed post of that particular book in the library mobile catalogue (m.liu.se).
Assume that you have retrieved the book, pictured below, in the library catalogue, and want to go to the shelf where it is placed. In order to do that, you read the QR code with your smartphone (you will need an appropriate QR code app). A web browser will open in the mobile phone, and you will be directed to a webpage where you can choose the alternative "Map". A map will then be displayed in your phone, stating the section in the library where the book is located.
Or, maybe you have already borrowed the book and need to renew your loan. The button "My loans" quickly leads you to the renewal function.
However, you might have finished reading the book, and are now looking for more books on the same subject, or by the same author. For this purpose, there are direct links placed further down on the same page.
