While UC Library Search lets you search the contents of the libraries at all ten UC campuses, it also allows you to narrow your search results to the contents of the UCM Library only. You can do this by choosing "UC Merced Catalog" from the UC Library Search menu.
After you do a search, look at the pulldown menu next to the search box. In this case, we've done a search for "mexico and politics and history." The search default is "Articles, books and more." The results of this search include the contents of UCM's library and the libraries at the other nine UC campus libraries (yellow arrow). To limit your search to UC Merced's library only, click "UC Merced Catalog" (yellow rectangle).
