The Public Library of Boca Raton (and most libraries which are federal depositories) have books in the "area handbook series" from the Library of Congress. That book for Haiti is ISBN 0844410446 and the latest edition was published in 2001 with Helen Chapin Metz cited as author. Those books are now on-line as "Country Studies". The Boca Public Library has the hardbound version in the reference section (call# R 972.93 Dom); that version of the book includes both the Dominican Republic and Haiti and is 590 pages.
