Law firms and the U.S. courts have proven extremely loyal to their word
processors. (Many still use WordPerfect!) If OpenOffice.org were to provide a
legal citation checker, much like a spell-checker, you could completely win over
the loyalty of this sizable niche market.

_Uniform System of Citation: The Bluebook_ 17th edition, ISBN: 999149183X is the
rule book for proper legal citation format. It is extremely rule-based, a pain
for humans to master, and therefore perfect for computer implementation. There
are strict rules for how words in case names are to be abbreviated, what is to
be italicized and what not, where commas and periods go, etc. One could probably
read the Blue Book section by section and figure out how to implement the rules,
but I'd be glad to provide advice if anyone tackles this project.
