92: Use of 92 was discouraged by 1920, with biographies going instead in the
call number for the subject the person was associated with.  In 92, the first
line is Cutter for the person written about, and the second line is an
initial or Cutter number for the writer.  DDC used geographical divisions
for the main place the person lived.

940-949: Decimal divisions for historical periods and parts of the country or
region.  For example, 942 England has 942.01-942.09 for historical periods
and 942.1-942.99 for parts of England.  Cutter numbers are used on first line
for cities or other localities.

940.911: Special 3-line call numbers for World War I units.

943: Special decimal subdivision 943.015 is Church history of the Protestant
movement (classified as a topic in German history).  943.015 over LA to LZ is
for Martin Luther, with a special scheme: the second line is L + alphabetic
form table (6) + special numbers putting authors roughly in alphabetical
order.

951 and 899.6 are both used for China, and 952 and 895.6 are both used for
Japan.  What basis if any for the distinction is not stated in the tables.

972: There is an odd decimal subdivision 972.0 (zero) for pre-Columbian
history.

973: Decimal expansions .1-.9 are for historical periods.  Geographical
divisions are in 974-979.

974-979: DDC uses a geographical order instead of the alphabetical order
here.  In the States' call numbers, subdivisions for books about counties or
cities are created by using Cutter numbers on the first line for the name of
the county or city, like 978N48 for City of New York; the second line then
has the usual Cutter number for author.
