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:
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.

You can request a UO Libraries' book held at any of our locations to be sent to your preferred pickup location--any of our branch libraries, as well as home delivery. 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. You must be logged in to your Library Account to see the request options.
If you only need a chapter from a print book the UO Libraries provides a service called Scan & Deliver where you can place a request to have a copy of the item made for your use (subject to copyright restrictions). To request a print chapter in LibrarySearch, click on the title then scroll down to "Request: Scan & Deliver." Complete the form with information about the chapter--including page numbers--to complete the request. You must be signed in to your Library Account to see the request options.
If the book you want is checked out from the UO Libraries, or if it's not available from UO Libraries, you can request it through the Summit system. Summit is an organization of academic libraries in the Pacific Northwest. Members can borrow materials quickly and easily among libraries.
To make a Summit request, you must be signed in to your LibrarySearch Account. Once you are signed in, you will be able to see the "Place Summit Request (about 5 days)" link (see examples below).
EXAMPLE: Book is not available from UO Libraries.
If you need an item that is not available through the UO Libraries, you can request it through our interlibrary loan service (ILL).
You can search hundreds of libraries from around the world using WorldCat. It is linked directly from the UO Libraries homepage (see below).
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).
On the next screen, you will log in to LibrarySearch to place your request.
After you log in, 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."
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 LibrarySearch account and go to the Requests section.
