Signature Books is famous for their "cutting edge" (OVER the edge, to most "traditionalists") books on Mormon subjects; e.g., New Approaches to the Book of Mormon: Explorations in Critical Methodology, The New Mormon History: Revisionist Essays on the Past (Essays on Mormonism Series), Early Mormonism and the Magic World View, Faithful History: Essays on Writing Mormon History (Essays on Mormonism Series), etc. This 2002 collection does not disappoint, in that regard.
Here are some quotations from the book:
"Both the brass plates and the Book of Mormon were written, according to Lehi, in the Egyptian language and not just Egyptian characters. Despite Hugh Nibley's efforts to make this extraordinary notion palatable, it is wildly improbable. Is one seriously to believe that for several generations Lehi's family was at home in the Egyptian language? Moreover, are we to believe that centuries before the Old Testament was translated into Greek (Septuagint), Lehi's kin had privately sponsored the translation of the entire Hebrew canon into Egyptian?" (Pg. 4)
"...we learn, for example, that the three (witnesses) did not experience the vision together; that Martin Harris's vision occurred separately. Both Harris and David Whitmer later testified that they also saw in their visions a table upon which rested a breastplate; the urim and thummim, the liahona, the sword of Laban, and brass plates---an interesting detail missing from the official testimony. The statement also fails to mention that the angel spoke, although it refers to the voice of God." (Pg. 81-82)
"Harris, for example, told several residents of Palmyra, New York, that he had seen the plates with his 'spiritual eyes.'" (Pg. 86)
"If the (eight) witnesses were shown an empty box or if ... it seems probable that at the signing of the testimony only some of the witnesses had handled them, that what was true for the group was not necessarily true for each man. Third, (Joseph) Smith may have produced a box containing the plates or perhaps something of similar weight. The witnesses were permitted to lift the box, but their view of the plates was visionary." (Pg. 104)
"During the last twelve years of his life, (B.H.) Roberts spoke with two voices regarding the Book of Mormon. When he could not come up with answers to his questions, he did not find it necessary to abandon his role as a general authority, nor to renounce his faith." (Pg. 145)
"The (Book of Mormon) conserves unacceptable translations of the KJV now clearly recognized as such from the stance of modern research." (Pg. 173)
"So far, I have tried to indicate that, far from being a miscnievous or malicious hoaxer, Joseph Smith was simply doing what the authors of the various biblical and extra-biblical pseudepigrapha were doing." (Pg. 333)
"A case in point would be Gordon H. Fraser, author of the polemical What Does the Book of Mormon Teach. One can scarcely imagine him welcoming Higher Critics of scripture to apply the same critical tools on Fraser's beloved Bible as he himself has used in vivisecting the Mormon scripture." (Pg. 334)
