Who's Who in American Art is a biographical hardcover directory of noteworthy individuals in the visual arts community in the United States, published by Marquis Who's Who, formerly by R.R. Bowker Publishing. The directory has also listed some individuals from Canada and Mexico, plus some American artists and arts professionals currently residing in other countries. The latest edition includes 11,000 biographies of artists, critics, curators, administrators, librarians, historians, collectors, educators, dealers, and conservators, of whom 9,000 are artists. The individuals featured in new 36th edition were obtained from nominations provided by current entrants, art associations, galleries and museums or from citations in professional publications. In many cases, though, the names are collected independently by Marquis research and editorial staffs, which use a wide assortment of tools to gather the most complete, accurate, and up-to-date information available.
