FIELD DEFINITION AND SCOPE
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. The technical report number is usually the primary means of
identifying a specific technical report.
Field 027 is repeatable for multiple ISRNs and STRNs associated with an item.
A fuller description of the STRN is given in field 027 (Standard Technical Report
Number) in the MARC 21 Format for Bibliographic Data.

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.
