This website searches both the 2006 IUCN database and the 1997 database. Therefore no need to check in the 1997 red list book. Might still want to check the most recent IUCN database as it comes online (i.e. currently is 2007).
Good link for Costa Rican specimens from the Tropenstation, Piedras Blancas National Park, Puntarenas
