This work is now online.

Published in 1992, the Encyclopedia contains nearly 1500 articles
including several short un-attributed entries in four volumes. The
text is approximately one million words, and over 1850 pages including
pictures, maps, charts, index, and appendices.

There were over 730 contributors from a wide variety of fields, most
of whom had LDS and academic backgrounds. A large number were
professors at Brigham Young University. Most individuals contributed
only one article and few submitted more than three or four. Notable
contributors include Mormon historians Leonard J. Arrington, and
Thomas G. Alexander, former Salt Lake City mayor Ted Wilson, noted
non-Mormon LDS historian Jan Shipps, authors Steven R. Covey, Gerald
N. Lund, and Richard Eyre, respected scholar and apologist Hugh
Nibley, and a few members of LDS hierarchy like Paul Evans, H. David
Burton, and Jeffery R. Holland.

The editor of the Encyclopedia of Mormonism, Daniel H. Ludlow, states
that he strove to make the volume as professional as possible. Most of
the articles are written by Ph.D.s in their respective fields. General
Authorities wrote little of the Encyclopedia; indeed, most
contributors from church hierarchy were only tapped to write articles
on the publications or institutions they directly administered or led.
For impartiality and perspective, several non-Mormons were asked to
write important articles. For example, Jan Shipps wrote on the
outsider's interpretation of Mormonism, and Richard P. Howard,
historian of the Reorganized Church of Jesus Christ of Latter Day
Saints, wrote on his branch of the Latter Day Saint movement.
