There are several ways to limit and refine your search results using the options in the filter panel on the left.
These options for limiting and refining are context-sensitive, and options for limiting are determined by your search terms and any previous limits you have set.
The first set of limits under "Refine your search" are the same across all search types and allow you to make important choices about what OneSearch results you will see.
Choosing "Library Catalog" allows you to find any physical items (books, CD, DVDs, maps, etc) that we own at the University Libraries.
As you scroll down, you'll see additional limits in the filters panel, including content type, publication date, library location, discipline, subject terms, and publication date.
You can click the box to the left of a filter to say that you want to only find entries with that characteristic. Or you can exclude entries with that characteristic by clicking on the red X on the right, which says "Exclude this item" when you hover on it.
Choose "Clear all" at the top of the Filters Panel to remove any applied limiters and start fresh.
