Matt Roper from the Neal A. Maxwell Institute of Religious Scholarship (formerly FARMS) has managed to track down, compile, and scan 556 publications discussing the Book of Mormon from between 1829 and 1844.

It is generally known and spoken of as the “Golden Bible.” Most people entertain an idea that the whole matter is the result of a gross imposition and a grosser superstition. It is pretended that it will be published as soon as the translation is completed. Meanwhile we have been furnished with the following, which is represented to us as intended for the title page of the work--we give it as a
