This microfilm contains materials published or distributed by Protestant Christian organizations in Cuba. Many are published or printed by independent evangelical groups and distributed by various denominations or churches, and this is indicated on the inventory of those items.

Most of the Protestant denominations represented in this microfilm have counterparts in English-speaking countries, and so, for the convenience of the researcher, their names are listed in English. However, there are also many independent Cuban churches, such as the Iglesia Apostólica de Dios de la Profecia, that may be unique to the island. While their names could be translated, this might be misleading. Therefore, their names are listed in Spanish in the microfilm inventory.

Materials pertaining to the Orthodox Church in Cuba are also included in this microfilm, even though the Orthodox Church is not a Protestant sect, since there is not enough material available from this organization to create a separate microfilm on this subject.
