To get started on your project, you should start by searching for your items first through the Search@UW and then through WorldCat before searching in the ISTC. This is the established workflow that will be most efficient and informative for you to complete your assignment.
WorldCat.org is a universally accessible database but UWM subscribes to WorldCat Discovery as a cataloging tool. Utilizing our institution's login opens up more in-depth search tools. Be sure you navigate to WorldCat by navigating to the UWM Libraries home page and then opening the "Search & Find" drop down menu and selecting the WorldCat option. You should not click the link that states, "This Item in WorldCat" that often appears at the bottom of a bibliographic record in Search@UW nor should you type WorldCat.org in the address bar of your web browser. These latter two options will limit you to the universally accessible version of WorldCat.
Often, when you look for an item in WorldCat you will find multiple records that are in fact identifying the same item. You will also find that each record identifies multiple holding institutions. So, what's going on?
Proficiency in WorldCat searching allows librarians to learn about the publication history of titles as well as the volume, condition, and locations of items. You can use WorldCat to determine how common or rare an item is and to determine who else holds the item. This information might affect collection management decisions such as acquisitions, weeding, and preservation needs.
