An online public access catalog (or OPAC) is a listing of all the items that the library has. It's like a card catalog, just the online format. The link to the UAH catalog is http://146.229.49.92/uhtbin/cgisirsi/wrJXFAriVY/x/183740004/60/1173/X. You can type in the title, author, or subject you are looking for and it will pull together a list of all the items that meet that criteria.
