the library has a unique call number. A call number is like an address:

State University library,
like many academic libraries in the U.S., uses the Library of Congress
Classification system for call numbers. This system uses a combination
of letters and numbers to arrange materials by subjects.

same call number can be written from

Numbers in Shelf Order
how call numbers are put in order in the Library of Congress Classification
system, look at each section of the call number.
does the call number mean?
the Library of Congress Classification system arranges materials
by subjects. The first sections of the call number represent the
subject of the book. The letter-and-decimal section of the call
number often represents the author's last name. And, as you probably
recall, the last section of a call number is often the date of publication.
this important to know?
Because books are classified by subject, you can often find several
helpful books on the same shelf, or nearby. For example, within the
same call number LB2395, there are other guides for college study.
Since the Library
of Congress Classification system arranges materials by subjects,
knowing the letter(s) for your subject area gives you a place to
start browsing the shelves.
