Description/Instructions

Field 027 contains an International Standard Technical Report Number (ISRN) or a Standard Technical Report Number (STRN) formulated according to specifications in the standards International Standard Technical Report Number (ISRN), ISO 10444, Standard Technical Report Number Format and Creation, ANSI/NISO Z39.23-1997, or Standard Technical Report Number Format and Creation (STRN), Format and Creation, ANSI Z39.23-1983, and assigned to a technical report. A technical report number is usually the primary means of identifying a specific technical report.

Number structure

The ISRN is composed of three parts: 1) a report code of alphanumeric characters that designate the issuing organization and, in some cases, a series; 2) a sequential group of numeric characters assigned by the issuing organization; 3) an optional addition that includes a country code and local suffix provided by the issuing organization. The report code and sequential group are separated by a double hyphen (–). The country code is preceded by a double hyphen (–) and the local suffix by a plus sign (+). Slashes and single hyphens may be used as subdividers within the report code and within the sequential group. These marks are carried in the MARC record.

A STRN is composed of three parts: 1) a report code of two to fourteen alphanumeric characters that designate the issuing organization and, in some cases, a series; 2) a sequential group of one to seven numeric characters assigned in sequence by each report-issuing entity; and 3) a local suffix, an optional element in which the issuing organization may place additional information.

The report code and sequential group are separated by a hyphen (-) and the sequential group and local suffix are separated by an ampersand (&) or a plus sign (+). Slashes may be used as subdividers within the report code (a maximum of two may be used) and within the sequential group (after the second digit). These marks are carried in the MARC 21 record. It may be difficult for the cataloger to distinguish a STRN from other numbers appearing on the piece since the STRN is not usually labeled as such. If the technical report contains a Report Documentation Page (Department of Commerce Optional Form 272), the STRN will appear in the box labeled "Report No." The STRN applies only to U.S. reports. Only one STRN should appear on a piece. In case of doubt whether a number is a STRN or not, use field 088 (Report number).
