We are currently experiencing a problem with links to the catalog for items that are on order. If you receive the Wowbrary newsletter, you may search for the titles in the Legacy Catalog and place holds there.
If you'd like to browse the library's collection of books on CDs (or other formats such as DVDs or large print books), you can do so through the catalog's Advanced Search feature. First, click on the Explore tab, then look for the search field in the top right corner of the page. Click on the Advanced Search link under the red Search box.
