Lately I’ve seen subject heading strings in OCLC records without a topical subdivision for example: $a Berlin (Germany) $y 20th century. Usually there would also be a $x History or $x Social life and customs, etc . I tried looking in the Subject Heading manual under H 620, but it isn’t clear. All the examples have a topical subdivision after a geographic heading. Is this type of subject heading kosher?

See H1647 http://www.loc.gov/aba/publications/FreeSHM/H1647.pdf

“1. General rule. Except as noted below, use the free-floating subdivision –History under topical headings, classes of persons, ethnic groups, uniform titles of sacred works, names of places, including jurisdictions that no longer exist, and corporate bodies, for descriptions and explanations of past events concerning the topic, group, sacred work, place, or organization.”

There follows a series of examples where –History is not used and then comes specifically:

“2. Chronological subdivisions.
a. Established chronological subdivisions. Use –History further subdivided by chronological subdivisions for specific time periods where they are established under headings for topics and places. Examples:
651 #0 $a United States $x History $y Civil War, 1861-1865.
651 #0 $a Japan $x History $y Heian period, 794-1185.
650 #0 $a Theater $x History $y To 500.”

So the answer is: Berlin (Germany) should have –History before the chronological subdivisions.

People make these mistakes all the time and the catalogs are riddled with them.
