The catalog tells you whether or not we have an item. If we have the item, the catalog will give you the item’s call number. Each item has a unique call number which is the item’s address.
A call number is a code made up of a series of numbers and letters. We use the Library of Congress Classification System to create a call numbers, which ensures that you can find the books you need.
This is what a call number looks like in the catalog:

All those letters and numbers mean something. And while it can be useful to know what they mean, it’s more important to know how they work. A call number is the book’s address.

Related books are often near each other, so once you’ve found what you are looking for, feel free to take a moment to look around and see if there’s anything that might be useful to you.
UDC Search is the catalog search at UDC. Through this single search box, you can find books, articles and other materials owned by the UDC library, and other libraries in the Washington Research Library Consortium.
Start your search using the search box above. This is also found on our library homepage.
Once you perform an initial search, you will be presented with filters on the left-hand side that will allow you to narrow your search.
You can also change what you are searching for, using the dropdown menu next to the search bar.

E-books are books, too! They just happen to be available to you online. Just like any of the library's databases, these can be used from anywhere with an Internet connection. When prompted, all you have to do is log-in using your UDC credentials.

E-books are available in many of the library's databases. You can try a few of them in the list below:
