Although Spain once nominally controlled the entire Caribbean, and although there are many archival riches on the region held within Spanish archives, it is often very difficult to find those sources. Even in the cases of Hispaniola, Cuba, and Puerto Rico, some of those sources are in archives outside of the AGI, and researchers will likely benefit from seeing those sources compiled.
Each entry/island on this page will contain an "official" index found on PARES and an "unofficial" index assembled by myself with contributions from other researchers.
