FAQ on SACO Subject Heading Proposals
- How do I know when to submit a proposal for a
new subject heading to SACO?
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 that in many cases it's also
necessary to search the name authority file because some subjects
are represented by name headings, or by subdivisions used under
name headings. 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.
Back to Questions
- Is my subject heading likely to be approved as
proposed?
The key to having a subject heading proposal approved
is to follow the general guidelines and those for various types
of headings that exist in the Subject Cataloging Manual (SCM)
(e.g., H 373 on UF references; H 1332 on biological organisms);
to carry out adequate authority research to help you formulate
the heading and its reference structure; and to provide citations
of that research in 670 (Sources found) and/or 675 (Sources not
found) fields in support of the proposed heading.
Generally, LCSH terms are approved on the basis of what is standard
in contemporary American English usage. Preference is given to
terminology and expressions in general use over jargon, and in
some cases over technical terms, especially when precision would
not suffer. Members of the Cooperative Cataloging Team are responsible
for providing an initial review of subject heading proposals from
SACO participants and will notify a contributor if a heading is
not formulated according to stated guidelines, or if appropriate
and sufficient authority research is not indicated. However, even
a carefully prepared and researched proposal is subject to change
by the weekly editorial meeting.
The purpose of the editorial process is to maintain the overall
consistency and cohesiveness of LCSH. The staff of the Cataloging
Policy and Support Office (CPSO) who are responsible for reviewing
new proposals and participating in the weekly editorial meeting
have an overview of the LCSH system as a whole. Sometimes overriding
general principles may affect the construction, style, or terminology
of the new heading being proposed. In other cases, selecting the
preferred form of heading may be a matter of judging the best option
among several different possiblities, and the judgment of the editorial
meeting may differ from the contributor. Members of the Coop Team
will notify SACO contributors of changes made to proposals at the
editorial meeting.
Back to Questions
- What is the purpose of subject authority research?
The purpose of doing authority research and listing the
sources consulted in 670 and 675 fields of the proposal form is
to demonstrate the form(s) in which the terms that are proposed
as the heading and UF references are found in existing literature,
i.e., to provide evidence that they have literary warrant, or to
document (in the 675) that no citation to the term can be found
in relevant sources. Results of authority research help in deciding
which term or phrase to select as the form of heading and which
to use as UF references as well as to determine appropriate BT
(Broader Term) references (5XX fields). Authority research also
helps in deciding whether a scope note that provides a definition
or usage statement is needed, or whether a parenthetical qualifier
is needed (e.g., for a term or phrase that has another meaning
in a different context).
Back to Questions
- Do proposals need to have more than one 670 (Sources
found) field?
The first 670 field should contain the citation to the
work being cataloged. SCM H 202 states that "It is seldom acceptable
to cite only the work cataloged as authority for a new concept." It
is necessary to seek corroboration or verification of the term
or phrase proposed as the heading in other sources. Any individual
work may or may not be accurate, may or may not be authoritative,
or may or may not present or advocate a particular point of view;
therefore most, but not necessarily all, proposals will need to
have more than one 670 or a combination of a 670 and a 675 (Sources
not found) fields.
Back to Questions
- What authority research is needed for obscure
topics or topics not likely to be found in sources other than in
the work being cataloged?
Although the topic may be found only in the work being
cataloged, other sources appropriate to the subject area in question
should be cited (in the 675) to demonstrate that the topic was
properly investigated. There may be some situations, for example,
an individual archaeological site or computer language, where the
only available information is found in the work being cataloged.
Remember in those cases, it is useful and important to cite pertinent
explanatory information from the work (in 670 $b) as succinctly
as possible.
Back to Questions
- Are some research sources preferred over others?
Generally, citation of authoritative reference sources
is preferred over citation of usage in titles to support the choice
of heading. Examples of authoritative reference sources are:
- Dictionaries or glossaries
- Encyclopedias
- Thesauri, and/or
- Indexes
Either print or electronic versions of these sources may be consulted.
Sources of this type present terms and phrases in context and
may include definitions, usage statements, and/or synonyms. They
may aid in selecting references or in drafting a scope note.
Finding usage of terms and phrases in titles in large databases
(e.g., LC database, OCLC's WorldCat, the WWW) may demonstrate
that a particular term or phrase is in use and has literary warrant,
but it doesn't necessarily indicate that it is the predominant
or best way of referring to a topic. Checking for usage in titles
is a good means of finding variant terminology for UF references.
Note: It is important to remember that sources
must be relevant to the topic being established. For example,
search dictionaries such as Webster's 3rd or Random House for
general topics; historical dictionaries or encyclopedias for
battles; scientific dictionaries or encyclopedias for scientific
concepts; chemical dictionaries for chemical names or processes;
Medical Subject Headings (MeSH) or Dorland's medical dictionary
for medical terms, the Art and Architecture Thesaurus (AAT)
for art concepts.
Back to Questions
- Is there a definitive list of preferred references
sources in each discipline?
No such list exists. Generally, the items selected for
the reference collections of academic, research, or public libraries
should prove useful. To get an idea of the types of reference sources
that have been consulted and cited for various types of headings,
you could look at the 670 and 675 fields of subject headings established
since 1986 ( i.e., subject authority records with the prefix "sh
86" or later).
Note: The SACO home page contains a "List
of Web resources for use in preparing SACO proposals" (developed
by Adam Schiff, University of Washington), which includes selected
authoritative sources, especially in the fields of geographic
names and natural history, that may be useful for authority research.
This is a "work in progress" and participants are invited to
send the URL of their favorite research site to
aschiff@u.washington.edu for
inclusion in the list.
Back to Questions
- How much research is considered to be enough?
SACO does not require that catalogers perform exhaustive
research. The goal is subject authority research that is good enough
to indicate a consensus of usage in relevant sources. The quantity
of authority work deemed sufficient will vary with the topic and
what the consulted reference sources reveal. If the information
found in the work being cataloged is confirmed in at least one
relevant, authoritative source, that is probably all that is needed
in most cases. If conflicting information is found in the first
two sources checked, further sources may need to be checked in
search of a "tiebreaker." It is sometimes necessary to weigh the
information found in various sources and to determine which source
is more authoritative or current.
Back to Questions
- Is it necessary to cite an "LC pattern" on all
proposals?
Not all proposals need a citation of an "LC pattern" in
a 952 (Local note) field. Citations of existing subject headings
generally support the style of a proposed subject heading while
citations of authority research in 670 and 675 fields support the
substance. It is helpful to look for analogous existing headings
to decide whether to propose a heading as a phrase or as a subdivision
under a main heading, or to determine what adjectival qualifier
is already in use for a particular nationality or ethnic group.
In those cases, the analogous headings should be cited as an LC
pattern in a 952 field. It is usually unnecessary to look for LC
patterns when proposing a subject heading for a named entity that
is established according to guidelines in the SCM (e.g., geographic
headings that are formulated according H 690 and qualified according
to H 810; buildings and other structures that are formulated and
qualified according to H 1334). In some cases, you might be misled
by following the pattern of an existing heading if it is not analogous
to your proposed heading (e.g., a geographic heading with extra
information in its qualifier to break a conflict). With named entities,
it is advisable to follow the rules in the SCM and cite the specific
instruction sheet followed in the 952 field.
Back to Questions
- Is it true that PCC proposals are preapproved?
Proposals from PCC libraries are considered preapproved
once these have been reviewed by the Coop Team and sent to CPSO
for editorial review and inclusion on the next tentative Library
of Congress Subject Headings Weekly List. That means that if no
report of a problem regarding a proposal is received from the Coop
Team within a reasonable amount of time, the proposed heading may
be assigned in the bibliographic record for the work being cataloged
and that record may be contributed to a bibliographic utility with
the understanding that it may need to be revised at a later date
if the subject heading proposal is changed at the weekly editorial
meeting.
Back to Questions
- Is there a way to track the progress of a proposed
heading?
Yes, currently there are two ways to do this:
- The "tentative" Library
of Congress Subject Headings Weekly List is posted on the SACO home
page. By viewing this list SACO participants may ascertain
the list number and date that a proposed heading is scheduled
for review.
- Once a proposal has been reviewed and approved, participants
may search the CPSO web
site for the official Approved Library of Congress Subject
Headings Weekly Lists to ascertain the form in which the
heading was approved for inclusion in LCSH.
If there are questions on the status of a proposal, not discerned
by the two searches above, participants should send an e-mail
inquiry to their institution's SACO liaison or to the SACO account
at saco@loc.gov.
