About: Joseph Smith is not considered to be either a Manifestation or a lesser prophet, but rather a sensitive person who was influenced by the spiritual forces Bahá'u'lláh released (Lights of Guidance, 2d edition, 510f.) Given Smith's merely human status, he is not considered to have had the ability to prophesy (ibid. 484). Nonetheless, Kenneth D. Stephens has attempted to demonstrate that Smith foretold the appearance of The Báb and Bahá'u'lláh. This is contained in the longest, though non-academic, exposition of the relationship between the Bahá'í Faith and Mormonism yet published, Stephens' <i>So Great a Cause! A Surprising New Look at the Latter Day Saints.</i>
References: Lights of Guidance, 510-11, has three paragraphs on Joseph Smith. George Townshend appears to be the first Bahá'í author to publish on Mormonism, producing The Conversion of Mormonism in 1911 and Why I am not a Mormon, in 1907. These are currently out of print. William Collins has written three excellent (and available) articles about Mormonism: "The Bahá'í Faith and Mormonism," in World Order, 15.1/2 (Fall 1980/Winter 1981); "The Bahá'í Faith and Mormonism: Further Reflections," in World Order, 17.3 (Spring 1983); and "Research Note: Mormonism and the Bahá'í Faith," in Journal of Bahá'í Studies, 3.2 (1990-1991).
Unfortunately <i>So Great a Cause</i> is unavailable (though try http://abe.com ). I recently corresponded with the publisher, asking if it was out of print because it's not listed at his site http://www.naturegraph.com/general/bahai/bahai.html , and if not, was it possible to post it online. He responded that it is no longer in print and no longer available from him, and that he does not have a digital copy of it. However, he would give permission to post it online (pending author's permission too).

<b>Update:</b> This is a good site, which would summarize a more "authoritative" interpretation of Mormonism and the Baha'i Faith than Mr. Evenson might provide: http://www.bci.org/prophecy-fulfilled/mormon.htm .
