Making Index Entries
====================

  When you are making index entries, it is good practice to think of the
different ways people may look for something.  Different people _do
not_ think of the same words when they look something up.  A helpful
index will have items indexed under all the different words that people
may use.  For example, one reader may think it obvious that the
two-letter names for indices should be listed under "Indices,
two-letter names", since the word "Index" is the general concept.  But
another reader may remember the specific concept of two-letter names
and search for the entry listed as "Two letter names for indices".  A
good index will have both entries and will help both readers.

  Like typesetting, the construction of an index is a highly skilled,
professional art, the subtleties of which are not appreciated until you
need to do it yourself.

index at the end of a book or creating an index menu in an Info file.
