National Service Center for Environmental Publications (NSCEP)
Publication Numbering System
The EPA publications numbering system was designed in 1991 to provide easier identification, tracking and dissemination of publications. Each publication number identifies:
- The responsible
organization producing the publication.
- A specific office/division
within the organization.
- An alpha descriptor
of the document type.
- Calendar year in
which the publication was produced.
- And the sequential number identifying how many of that type of publication were produced within that particular organization during the calendar year.
Example: 200-B-96-001
indicates a publication from Administration & Resources Management (see
Table 1);
a reference (see Table 2);
produced in 1996; and the first publication of that type issued in the year.
