Definition

Field 027 contains a Standard Technical Report Number (STRN) or an International Standard Technical Report Number (ISRN) assigned to a technical report. The technical report number is usually the primary means of identifying a specific technical report.

The STRN is formulated according to Standard Technical Report Number (STRN), Format and Creation, ANSI Z39.23-1983. A STRN has the following parts:

  • Report code. Alphanumeric characters that identify the issuing organization and, in some cases, a series.
  • Sequential group. Numeric characters assigned in sequence by each issuing organization.
  • Local suffix. An optional element in which the issuing organization may include additional information.

The report code and sequential group are separated by a single hyphen (-). The sequential group and the local suffix are separated by an ampersand (&) or plus sign (+). Slashes (/) may be used as subdividers within the report code and within the sequential group.

The 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. An ISRN has the following parts:

  • Report code. Alphanumeric characters that identify the issuing organization and, in some cases, a series.
  • Sequential group. Numeric characters assigned in sequence by each issuing organization.
  • Country code and local suffix. An optional element in which the issuing organization may include additional information.

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.

Printing

 Field 027 subfield ‡a prints as the last note. If the record contains field 022, it prints as the last note and 027 prints as the next-to-last note. Subfield ‡z does not print.
 

Only the first 027 field prints if the record has multiple 027 fields. If the first 027 field does not have a subfield ‡a, no STRN prints, even if subsequent 027 fields have valid numbers in subfield ‡a.

The print program supplies STRN before the number for both the Standard Technical Report Number (STRN) and the International Standard Technical Report Number (ISRN).
