## 1991 Mathematics Subject Classification |

- The search is not case-sensitive.
- The Boolean operator,
**Or**, is the default between words within a keyword box; adjacency is not assumed. - To
**And**search terms, enter text into the two keyword boxes. - For exact word matches, use quotes and spaces. For example, for
**linear**but not**nonlinear**, enter**" linear "**. - For exact phrase matches, use quotes, e.g.
**"optimal control"**. - Wildcards are not allowed.

The Mathematics Subject Classification (MSC) is a system used to categorize items covered by Mathematical Reviews and Zentralblatt für Mathematik. The current classification system has been used since 1991 (a few minor changes and additions were made in 1995). The MSC is broken down into over 5,000 two-, three-, and five-digit classifications, each corresponding to a discipline of mathematics (e.g., 62 = Statistics; 62N = Engineering statistics; 62N10 = Quality control). The 1991 Mathematics Subject Classification is being completely revised. The new classification, MSC2000, will be used starting in the year 2000.
