Number Structure: (027 Standard Technical Report Number - Input Conventions)
The International Standard Technical Report Number (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. 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; and,
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.
Examples:
027 ## $aFYHU/PF/2--80/12+MAGN
027 ## $aWBK-MTT--89/64--DE
