The Quotations Archive
All the quotations that fit the guidelines are stored at a publicly

The index is labeled either ``exact'', or ``incomplete''. If you
can give the exact wording to a quote marking ``incomplete'',
please write firstname.lastname@example.org. We are trying to keep paraphrasing
to a minimum.
