Arrangement of Government Publications
The Superintendent of Documents (SuDoc) classification system was developed in the library of the Government Printing Office and has been in use for over 100 years. The SuDoc classification system is based on the current organizational structure of the Federal Government.
The SuDocs numbering system is a classification system that groups publications by the same government author such as publication of the Interior Department. Keep in mind that SuDoc numbers are grouped by agency not subject.
All SuDoc call numbers begin with a capital letter (or letters) representing a government department or agency.
For example, if one were looking for the following title, Air Quality in the National Parks on the shelf, the Sudocs call number for this title is I 29.2: AI7/3.
(I) stands for the Department of the Interior
(I 29) is the Sudocs classification for the National Parks Service
(I 29.2) the number after the decemal point indicates the type of publication. In this case (.2) is a general publication. Keep in mind that the number after the decemial point is not a decimal, but rather a whole number
(I 29.2: AI7/3) the number after the colon represents individual book numbers, dates, or can be a letter and number. In this example the number after the colon is a cutter number which is used when there is no numbers to identify the publications and dates are not appropriate for identification.
