Signature Books is an American press specializing in subjects related to Utah, Mormonism, and Western Americana.

Among those present at Signature Books's 1980 inception were George D. Smith and Scott Kenney, assisted by a board of directors composed of historians and business leaders: Eugene E. Campbell, Everett L. Cooley, David Lisonbee, D. Michael Quinn, Allen Dale Roberts, and Richard S. Van Wagoner; and an editorial board consisting of Lavina Fielding Anderson, Maureen Ursenbach Beecher, Davis Bitton, Orson Scott Card, and Jay Parry.

Signature has also published noted studies of well-known early Mormon theologians such as James E. Talmage, B. H. Roberts, Orson Pratt, Parley P. Pratt, Brigham Young, John Widtsoe, and award-winning biographies of significant early Mormons such as, Joseph Smith, Sidney Rigdon, Wilford Woodruff, John Taylor, as well as a biography of thirty three of the plural wives of Joseph Smith.

[4] These include D. Michael Quinn, Lavina Fielding Anderson, Brent Metcalfe, David P. Wright, Dan Vogel, Grant H. Palmer, Stan Larson, Simon G. Southerton, H. Michael Marquardt, David J. Buerger,[5][6] Edward J. Ashment,[7] Janice Merrill Allred, Paul Toscano, and Maxine Hanks.

In its continuing assault upon traditional Mormonism, Signature Books promotes with its recent and dubiously titled work, The Word of God, ...naturalistic assumptions...in dealing with Latter-day Saint belief.

[14][15] In 2004, Signature Books posted on its web site a speech given by John Hatch, in which Hatch said, "After reading the (FARMS) reviews myself, it appears to me, and is my opinion, that FARMS is interested in making Mormonism's past appear as normal as possible to readers by attacking history books that discuss complex or difficult aspects of the church's past.

"[16][17] The friction between the two groups largely wound down, beginning when FARMS was assimilated into Brigham Young University's Neal A. Maxwell Institute for Religious Scholarship in 2006.
