How do I create information on the library in order to display them in the online catalog ?

The online catalog homepage contains a link called «Information about the library» that displays an information page. If you’d like to edit this page, create an information page in a word processor.

Then transform this page in a picture by making a screenshot of it, display the dialog box for configuring the Web Public Search (in the Maintenance) and paste the picture in the Info picture tab.
