How to read an LC Call Number

Library of Congress (LC) Call Numbers are like an item's address to help you find where it lives on the shelf. Each letter stands for an academic discipline. In the image below, L is for Education, LD is for Individual Institutions - United States. Can you guess which institution is at LD 4363 .U55 2006

To read a call number, read the number from left to right or top to bottom as follows:

  1. Alphabetically (L before LC, LC before LD)
  2. Numerically (4362.3 before 4363
  3. Alphabetically (.A before .B
  4. Decimal order (.U2 before .U5 or .U55
  5. (Sometimes there are more pieces in alphabetical then numerical order here)
  6. Finally, chronologically (1985 before 2006) This is year of publication and may or may not be included.

Lastly, the shelf is organized from top to bottom in sections, so you'll zig-zag down each section to look for your call number before moving to the next section. 

Bonus: You can also click the "Locate" option in LibrarySearch to see a floor map with the number of the shelf your item is on.

Search for Books and eBooks

In response to the ongoing COVID-19 emergency, access to the UO Libraries and many services have changed. Summit borrowing is suspended until further notice. For the latest updates on UO Libraries' COVID-19 response, please see https:/

Use LibrarySearch to locate print and e-books held in the UO Libraries. Remember you can use keyword, title, author or subject to locate items.

To look for print or ebooks available in the UO Libraries change the drop down menu to 'UO Libraries' (see below). This will limit your search to books, ebooks, and similar items, and will remove articles from the results. After you've done the search, limit to just print books or ebooks by going to "Refine My Results > Resource Type" on the left and select these options (see below).

Request a Print Book

You can request a UO Libraries' book held at any of our locations to be sent to the Knight Pickup Window, to the Law Library for curbside pickup, to the Portland Library & Learning Commons for curbside pickup, or to to your home address. To do this click on the book's title and then scroll down to "Request Options," select the "Request UO Item" link, and select your preferred delivery option. If the book is currently checked out this option also serves as a way to recall the book, although returns have currently been suspended. You must be logged in to your Library Account to see the request options.

Beyond UO Libraries: Interlibrary Loan

If you need an item that is not available through the UO Libraries, you can request it through our interlibrary loan service (ILL).

We are only able to borrow through ILL for current UO faculty, students, and staff at this time to support remote teaching and learning. Please note: Due to the ongoing COVID-19 pandemic, many libraries around the country and world are closed to employees and not fulfilling ILL requests. Obtaining material from other libraries is taking much longer than usual and borrowed items will be quarantined for three days upon arrival. Please use ILL judiciously.

Start your search:

You can search hundreds of libraries from around the world using WorldCat. It is linked directly from the UO Libraries homepage (see below).

Request an item:

If you find an item you want in WorldCat, look for the green button that says "Request Item Through Interlibrary Loan (about 10 days) (see below).

Log in to the ILLiad system:

On the next screen, you will log in to the interlibrary loan request system, or ILLiad. If you have never used ILLiad, you will be prompted to set up an account the first time you log in. If you need help logging in or resetting your ILLiad password, contact the ILL staff at 541-346-3055 or

Submit your request:

After you log in to ILLiad, the request form may automatically fill in with the item's citation information. If not, fill out the form with as much information as you have about the item, e.g., author, title, publisher, date. When you are done, click "submit."

Check the status of your request:

You will get an email when your item has arrived and is ready for pickup. To check the status of your request, log in to your ILLiad account.
