The Albertsons Library uses the Library of Congress classification system to arrange books on our shelves.
The first two lines describe the subject of the book. The third line often represents the author's last name. The last line represents the date of publication.
Read call numbers line by line.

The third line is a combination of a letter and numbers. Read the letter alphabetically. Read the number as a decimal, eg:
.C65 = .65 .C724 = .724
Some call numbers have more than one combination letter-number line.
The last line is the year the book was published. Read in chronological order:
