Do you mean that you want to produce several completely different letters
(say) depending ont he value of one or more fields in the Access database?
If so, the simplest appraoch is to do one merge for each letter and either
create an Access query to select the records for each merge, or do it using
the filtering facilities within Word.

If you mean something else, could you give an example? It may help if you
can tell us the version of Word and Access.
