Browse Mathematics Books by Call Number

To browse books on subjects in mathematics, use the links below to go to the page in the catalog on which a subclass begins. Due to restrictions on linking to a range of different call numbers in the Classic Catalog, you may have to scroll down to find the first book on a given subject.

What Are Call Numbers?

Washington WashU Libraries uses the Library of Congress Classification System (LC) to group books according to subject on library shelves. Each book has a unique call number, which acts as the book's address - it tells you exactly where to find the book on the shelf.

Most books in Mathematics (QA) will be found on Level B of the Olin Library.

What Do Call Numbers Mean?

LC call numbers divide books into classes, subclasses, topics, and subtopics.

For example, Fermat's enigma : the epic quest to solve the world's greatest mathematical problem by Simon Singh has the call number: QA244 .S55 1997.

On the book spine, the call number would appear like this:




is the class and subclass. Q is Science and QA is Mathematics.

  • Read the first line in alphabetical order: When there are two letters, Q comes before QA, which comes before QC, etc.

is the classification number for the subject. 244 is Higher congruences, residues. Fermat's Theorem.

  • Read the second line as a whole number: 80 comes before 793, for example.

is a combination of letters and numbers that usually represents the author or publisher's name.
It may also represent a more narrow topic or the author. In this case, .S55 represents the author, Simon Singh.

  • Read the letter alphabetically but read the number as a decimal. So .P43 comes after .P422

is the year of publication, and identifies separate editions of a text.

  • Read in chronological order.
