H 860 Subdivisions Further Subdivided by Place


BACKGROUND: Until 1992, the preferred method of combining a subject heading with both a topical subdivision and a geographic subdivision was to interpose the place name between the heading and the topical subdivision (cf. H 870). However, a restricted number of subdivisions were authorized for further subdivision by place to form headings of the type [topic]–[topical subdivision]–[place]. Example:


650 #0 $a Construction industry $x Law and legislation $z Maryland. 


The Subject Subdivisions Conference that took place at Airlie, Virginia, in 1991 recommended that the standard order of subdivisions be [topic]–[place]–[chronology]–[form].


In 1992, it was decided to adopt that order where it could be applied. Toward achieving the recommended order, new subdivisions for which geographic orientation is logical are now established with authorization for further subdivision by place. On a case-by-case basis, subdivisions not previously divided by place are being authorized for geographic subdivision.


Note: From 1977 until 1989, certain subdivisions were authorized for exceptional treatment allowing a place name to be located either before the subdivision, after the subdivision, or in both places, for example, Blacks–Latin America–Study and teaching–United States. That practice was discontinued in 1989.


1. Free-floating subdivisions. Free-floating subdivisions that are authorized for further geographic subdivision have the notation (May Subd Geog) on the lists of free-floating subdivisions in H 1095-H 1200. Use these subdivisions divided by place if required by the work in hand. Example:


650 #0 $a Chemistry $x Study and teaching $z Maryland.


2. Non-free-floating subdivisions. Use subdivisions that are established in the subject authority file with authorization for geographic subdivision divided by place when needed. When establishing new main heading-non-free-floating subdivision combinations, follow the instructions in H 364 sec. 1 to authorize further subdivision by place when appropriate.


3. Multiple topical subdivisions. When combining a main heading with a place name and more than one topical subdivision, place any needed geographic subdivisions following the last subdivision that is authorized for further subdivision by place. For example, the following subdivisions are on the pattern heading list of free-floating subdivisions used under types of educational institutions (H 1151.5):



–Finance–Law and legislation (May Subd Geog)

–Services for (May Subd Geog)

–Services for–Contracting out (May Subd Geog)


Therefore, the following headings may be constructed:


650 #0 $a Medical colleges $z California $x Finance.

650 #0 $a Medical colleges $x Finance $x Law and legislation $z California.

650 #0 $a Universities and colleges $x Services for $z Minnesota.

650 #0 $a Universities and colleges $x Services for $x Contracting out $z Minnesota.
