This version of the Bible is significant because, for the first time, a mechanically printed, mass-produced Bible was made available directly to the general public which came with a variety of scriptural study guides and aids (collectively called an apparatus), which included verse citations that allow the reader to cross-reference one verse with numerous relevant verses in the rest of the Bible, introductions to each book of the Bible that acted to summarize all of the material that each book would cover, maps, tables, woodcut illustrations and indices.
