OCLC Abstracts Says You and your users can now keep track of your favorite items in WorldCat through tags—keywords that help you classify or describe an item. Tags are displayed in search results lists and may help you find similar items or organize items in a way that makes sense to you. You can add as many tags as you would like to an unlimited set of items. You can view and maintain all of your personalized tags from your WorldCat profile page. Plus, you can also browse items using the tags other people have contributed.
