Information:
The Curriculum Objective (658 tag) of the MARC 21
bibliographic format contains index terms for
curriculum or course-of-study objectives that are
applicable to the contents of the material being
described. The curriculum objectives, curriculum
codes, and correlation factors recorded in the 658
field come from standard published lists. The list
is identified in subfield 2 (Source of term).
It is very important to complete all the information
in the subfields when sharing bibliographic records
with other libraries. It is especially important to
complete subfield 2, the source of the term, since
this identifies where the term originated. The
curriculum objectives for Ohio (ohco in subfield 2)
may be very different than the curriculum
objectives for a "local" site in Texas for example.
Subfield a contains a term describing the
curriculum or course-of-study objective. Subfield b
contains an objective that is secondary to that
contained in subfield a. Subfield c is a coded
representation of the curriculum objective recorded
in subfield a. The code is generally assigned by
the national or state agency that developed the
curriculum objectives. Subfield d describes how
closely the item correlates to the curriculum
objectives in subfield a. The terms usually used
are: slightly correlated, moderately correlated,
and highly correlated. Subfield 2 contains the code
from the MARC Code List for Relators, Sources,
Description Conventions that identifies where
the index term originated.
