Hi @olray, the “my catalog” feature is still available, however, it will be deprecated later this year as per the post below.
When you are logged into the network, this link https://[pressbooks domain]/wp/wp-admin/index.php?page=pb_catalog will take you to the user catalog page and there are instructions to Show/Hide books on that page. Your own catalog page can be viewed at https://uw.pressbooks.pub/wp/wp-admin/index.php?page=pb_catalog when you are logged in.
Our support team can help you find other alternatives, I think this catalog page for your faculty member would be a nice way to showcase their work.
