13.1 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 "Indices" are 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 skilled art, the
subtleties of which may not be appreciated until you need to do it
yourself.

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