(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.
