WestCat is WIU Libraries' online search tool for finding books, periodicals, DVDs, and other materials. It is located under the book tab, which is the default, on the WIU Libraries' homepage.
I-Share is where you turn when WestCat does not have what you need. It is the online public catalog for 86 CARLI libraries (Consortium of Academic and Research Libraries in Illinois). You will find a link to I-Share under the Books tab in the middle of the library homepage.
