Search MSC Help Topics
Enter a keyword or phrase or a 2-, 3-, or 5-digit classification
Initially the cursor is in the blank text input box under OR Search Classifications, where you may enter a keyword or phrase or a 2-, 3-, or 5-digit classification. Enter your search criterion. Following are some guidelines to keep in mind when entering your search criterion:
- MathSciNet searches are not case-sensitive.
- The typical Mathematics Subject Classification code consists of five characters, corresponding to the hierarchical classification scheme used in the construction of the Mathematical Reviews Database. Classifications may be entered as 2-digit codes (e.g. 51, for the top level "Geometry"), or as 2-digit+1-letter codes (e.g.51A, for the second level "Linear incidence geometry"), or as 2-digit+1-letter+2-digit codes (e.g. 51A05, for "General theory and projective geometries"). There are also generic codes, such as 51-04 ("Explicit machine computation and programs"), corresponding to each 2-digit code. There is an older system of codes (not in MSC 2010) such as 30.50, but these cannot be searched from this screen. Enter the corresponding 2-digit code (30, in this example) to see a listing of codes that include these older codes.
- The wildcard character is the asterisk (*).
- Enclose phrases in quote marks (").
Once the search criterion has been entered, click the Search button. Search results are displayed as a list of classifications with their text descriptors. Link to items that have been assigned a classification by clicking on the adjacent headline list icon.
a 2-digit classification
Instead of entering a keyword or classification, you may choose to select a 2-digit classification from a pull down menu. Click on the arrow to the right of the box and then make a selection from the pull down menu. Click the Search button. Search results are displayed as a list of classifications with their text descriptors.
the entire 2010 MSC in PDF
Here is a copy of the publication Mathematics Subject Classification 2010, which is updated and published periodically. It is in PDF format. There are no links to items in MathSciNet.
From the list of classifications that is displayed once you have completed a search, you can click on any classification code that appears as a link. This will expand the classification. You can continue to expand classifications as long as the classification is linked. If you click on the adjacent headline list icon, you will obtain a headline list matching the selected MSC. From this screen, full items can be selected for display.
Note: 2-digit classifications do not have links to headline lists as most of them produce cumbersome results.
