In my earlier booklet The Book of Abraham Papyrus Found, published in October 1975, it was shown that Joseph Smith did not correctly represent the Book of Abraham text as to what was written on the Hor Sensen Papyrus. It was also shown that Joseph Smith did not understand the ancient Egyptian language when working on the Book of Abraham. These Egyptian Papers are issued in this present publication to reinforce the knowledge that Joseph Smith knew nothing on how to correctly render the papyrus characters into the English language. Students of the Book of Abraham problem should be aware that this is one of the great values to having the Joseph Smith Egyptian Papers published.
The manuscripts included in this compilation were written in English but were based upon the Egyptian papyri which were in the possession of Joseph Smith. The numbering of the manuscripts and the handwriting identification was derived from the list published in the LDS Church publication BYU Studies Vol. 11, No, 4, page 351. These documents were first published by Modern Microfilm Company of Salt Lake City, Utah in April 1966. While at that time these manuscripts had not been numbered and labeled, it is nevertheless a fact that the manuscripts do represent Joseph Smith's dictation to his scribes and also his own handwriting which appears on part of Egyptian Manuscript No.4.

Most interesting site. Author is VERY neutral and the way he deals with BOA almost suggests that he is a RLDS since they do not hold BOA as ‘inspired’. But once again, very balanced and not afraid to say that Nibley, et al are screwed up.
