Books are wonderful, in-depth sources for many topics. They are usually more academic than background resources, can spend more time digging into a topic, and are usually not as challenging to read as scholarly journal articles.
A book doesn't need to be read cover-to-cover to be used for research! Many students use individual chapters or sections of a book.

The books on our shelves are arranged using the Library of Congress Classification system. Each book in the library has a unique “call number”, which is a combination of letters and numbers that are used to place books in alphabetical and numerical order. When you find a book in our online catalog, you can use the call number to find the book. The call number is placed on the lower part of the spine of the book.
In our catalog, the call numbers are displayed as a single line, but the spine label displays the call number as 3 to 5 lines. The call number is always read from left to right, then from top to bottom (when applicable).

Here are a few basic principles to help you understand how to use the call number to find a book on the shelf:
| Order on Shelf | First | Second | Third | Fourth | Fifth | Sixth |
|---|---|---|---|---|---|---|
| First Line | H61 | H61 | H62 | H62.3 | H62.5 | HA17 |
| Second Line (post-decimal) | .S4475 | .S74 | .K37 | .C547 | .U5 N354 | .V64 |
| Last Line (Year) | 2010 | 2015 | 2019 | 2018 | 2010 | 2016 |
