Digital LIbrary of the Caribbean (dLOC). This website privides (mostly) bibliographic records for materials held at several dozen research libraries, both in the Caribbean region itself, and in a few U.S. libraries (especially from the state of Florida). Not many of these records lead to full texts. There isn't a great emphasis on strictly literary materials, but the site is very useful for identifying primary and secondary sources on the history, economy, geography, politics, and culture of the region. It includes a particularly strong sub-section on voodoo.
