The protocanonical books are those books of the Old Testament that are also included in the Hebrew Bible and that came to be considered canonical during the formational period of Christianity. The term protocanonical is often used to contrast these books to the deuterocanonical books or apocrypha, which "were sometimes doubted" in the early church, and are considered non-canonical by most Protestants.
