In the Gallucci-Cirio Library:
Here is a call number for one of our books using the Library of Congress Classification System:
Call numbers begin with one or two letters and are organized alphabetically on the shelves. These letters describe the general subject of a book. (DS = History of Asia)
The second line is a number, which gives more detail on the specific subject matter of the item. This line is read numerically. (559.44 = Vietnamese Conflict)
The third line often represents the author's last name, and read as a decimal. (S = Smith)
The last line is the date of publication and is read chronologically. (1992)
You will notice that if a book's spine is slim, you may have to pull the book
out from the shelf a bit to read the Call Number.
