Derrell C. Roberts Library: Library of Congress Call Numbers
Reading the LC Call Number
LC call numbers begin with letters. In the online catalog, typical LC call numbers look like:
HB3505 .E44 1992
On book spines, or labels on other materials, LC call numbers are arranged vertically and would typically look like:
You would first look for the "HB" section. All the books whose call numbers start with HB will be together on the shelf.
You then look for the "3505". Remember this is a whole number, three thousand five hundred and five. Some books may have a decimal in this number, breaking the topic down more. All books with HB 3505 will be together on the shelf, with HB 3505 coming before any that may have a decimal after the 3505.
You then move to the next line, ".E44". Any number after the "." here is read as a decimal. You would find the books that have HB 3505 .E and look for .E44. One way to read it is E .44. This decimal is important to remember, ".E6432" would come BEFORE ".E705" which would be BEFORE ".E9".
The last line is the date the book was published, 1992. There can be books that are re-printed so they can have different dates here. So 1990 would come before 1992.
Some call numbers are preceded by a location prefix indicating that the item is shelved in a specific location and may have loan restrictions. For example:
REF - Reference item located on the Reference shelves on the 1st floor, East Wing. These books do not check out.
ROBERTS CIVIL WAR COLLECTION- Reference items located in the archive on the 1st floor, West Wing. These books do not check out but may be viewed by appointment. The ROBERTS CIVIL WAR COLLECTION are from the personal collection of Dr. Derrell C. Roberts, former president of the college for whom the library is named.
The books that do not have a location prefix should all check out.
This is an example of a SuDoc number. It looks different from the LC number, but you still read it basically the same. Just follow the letters and numbers to find your item.
