8 STANDARD NUMBER (OR ALTERNATIVE) AND TERMS OF AVAILABILITY AREA
Introductory The area may be repeated when an item has more than one standard number (or
note alternative)
A. because it is issued in more than one format or by more than one publisher, distributor, etc.
or
B. because it has a standard number (or alternative) for the individual unit and also a standard
number (or alternative) for the whole group of which it is a part.
In both cases, the standard number (or alternative) that specifically identifies the item being described is
given first. Other numbers (e.g. for the whole group, for other publishers) are given next, as repetitions of
the area.
If the title of the whole group is given in area 6, the standard number (or alternative) for the whole group is
not given with it, but is given in area 8, with the standard number(s) (or alternative(s)) for the individual
unit(s).
Each standard number (or alternative) recorded may be followed by any qualification needed to identify it
further and/or by its terms of availability and/or price, which may also be followed by a qualification.
Standard numbers (or alternatives) that are repetitions of the area must be qualified.
e.g.
. – RK 11719 (stereo)
Standard numbers (or alternatives) appearing in the item that relate to its bibliographic history (e.g. the
label name and issue number of a previous issue of a sound recording) are not given in area 8. When
considered important, they may be given in area 7.
