You can search both the U of I Library Catalog and the I-Share Catalog via a single interface. I-Share is a shared public catalog for 86 CARLI (Consortium of Academic and Research Libraries in Illinois) member libraries. The Library Catalog has replaced the older ClassicCatalog, although the Classic Catalog is still available to use. You can search the local U of I Catalog through either the Library Catalog or the Classic interface. We are currently transitioning to the new library catalog from the Vu-find catalog you may have seen before, so some links may still lead to the Vu-find catalog.
Here are some of the features you'll find in the Library Catalog:
A single simple search box
Refine search by subject, title, topic, language, format, and more
Search the U of I library catalog or all I-Share libraries at once, including item status and location information
Request UIUC items
Log in using your NetID and password

Advanced search options
Researchers can still use the Classic Catalog. This catalog allows for Call Number and Subject heading browsing.
