Eligibility - Who can join SACO?
It is highly recommended that catalogers consult
with their supervisors before beginning to send
forward subject or classification proposals.
SACO participation is currently not an
institution-based program. Any individual
cataloger at any institution who needs a subject
heading or LC classification number not found in
LCSH or in the LC schedules may send forward
a proposal to SACO.
Eligibility - Continued
There are no membership fees to join the SACO Program.
Requirements include having a basic knowledge of the procedures and guidelines contained in the
1) Subject Cataloging Manual: Subject Headings (SCM), and familiarity with
2) LCSH
3) Free-Floating Subdivisions: An Alphabetical Index,
4) MARC 21 Authority Format, and
5) Standard reference sources.
When to submit?
If you are cataloging a work on a discrete, identifiable
subject and after searching a current version of the
subject authority file and checking appropriate free-
floating subdivision lists, you do not find a specific
subject heading to use, it's time to consider making a
proposal.
Remember to search the name authority file.
Some subjects are represented by name headings, or
by subdivisions used under name headings.
When - Continued
It may also be helpful to check bibliographic records
for works similar to what you are cataloging to see
what subject headings have been assigned to them.
You might find that an appropriate subject heading
does exist in LCSH that uses another term or phrase
than your work does.
In that case, you might consider proposing a
UF (Used For) reference (4XX field) to the existing
heading from the terminology used in your work.
Principles to Remember
Principles that govern the formation of new subjects are:
1) Specificity, and
2) Natural word order
However, some earlier practices still exist in assigning headings.
Principles to Remember - Continued
LCSH reflects current and past policies of subject heading construction
LCSH still contains headings for subjects that have not been written about in many years and contains “old-fashioned” terms
