Once I've identified a book I want in the catalog and know its call number, how do I know where to find it in the library?
Click the "location" (often Pius Library) shown in the catalog for the book you want. That will link you to the current location guide, which indicates which materials and call number ranges you can find on each floor. Printed location guides are also available at the service desks on the first floor, and near the catalog computer terminals elsewhere in the building.
When in doubt, feel free to ask any library employee to help you!
