Problems in catalog data can make it harder for patrons to find and use your library resources. For library staff, problems may make your reports and analyses of metadata incomplete or misleading. By searching for different types of problems directly, we can identify and resolve many issues before they cause any more trouble. In this session, we will look at an expanded collection of Alma Analytics reports and accompanying websites that everyone can use to find problems in their own catalogs, and modify for their library's specific needs. We will also look at tools for monitoring your catalog for new problems so that they can be fixed quickly and prevented from coming back.
