Mathematics Subject Classification

The Mathematics Subject Classification (MSC) system is an alphanumeric ordering system for categorizing or arranging mathematical topics, similar to how a library arranges or orders their books on the shelves. The system was invented by the American Mathematical Society based on two major mathematical publishers: Mathematical Reviews and Zentralblatt MATH. The MSC system is used by many journals of mathematics which ask authors to list the MSC subject codes in their papers when submitted for publication.
