The Organization of SuDocs Numbers

Government Documents at CSU are organized according to the SuDocs (Superintendent of Documents) classification system which groups together publications by the same government author. Within an agency or department, publications are grouped by subordinate organization. The purpose of this system is to logically relate and physically arrange each item so that all publications of a single agency or department may be found together.

Examples

An example of a SuDocs call number: HE20.2:H81

Explanation of the example:

20. Represents the subordinate bureaus and office within the issuing department or agency (Public Health Services)

2: Indicates the publication type (General Publications)

H81 Represents the key word of the publication title (National Household Survey on Drug Abuse)

Finding Publications

Location of SuDocs Numbers:

In the CSU Catalog: I-Share, government documents are designated with the abbreviation: DOC. The abbreviation serves as a location device to tell where the item is shelved. DOC is not included as a part of the SuDocs number. SuDocs numbers are located on the upper left front cover (not the lower spine) of the print publications and are generally printed in horizontal fashion.

How Documents Are Shelved:

SuDocs is not a decimal system. Documents are shelved in alphabetical and then in numerical order. Numbers between punctuation are treated as whole numbers. Each section of the number should be read one at a time in order.
