International Standard Technical Report number (ISRN) or a Standard Technical Report Number (STRN) copied from subfield $a of field 027 of the MARC bibliographic record that represents the description of the item for which a separate holdings record is created.
May also contain any canceled or invalid numbers from subfield $z of field 020 (International Standard Book Number) in the bibliographic record. The ISRN and STRN are 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 (STRN), Format and Creation, ANSI Z39.23-1983, and assigned to a technical report.

Number Structure - ISRN is formulated according to International Standard Technical Report Number (ISRN), ISO 10444 or Standard Technical Report Number Format and Creation, ANSI/NISO Z39.23-1997. It is composed of three parts: 1) 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.
