This bulletin was first issued in 1979 as "How to" #2 and written by then National Register historians Marcella Sherfy and W. Ray Luce. Patrick W. Andrus, historian with the National Register of Historic Places, and the authors revised the text and produced the 1990 version of the bulletin, renamed National Register Bulletin 22, which included a discussion of historic properties of the World War II period. The examples cited in this third edition of the bulletin are derived largely from the essay that Carol D. Shull and Beth L. Savage prepared for the "Preserving the Recent Past" conference of 1995: "Trends in Recognizing Places for Significance in the Recent Past," which summarized recent listings of properties under Criteria Consideration G. The National Park Service prepared this bulletin pursuant to the National Historic Preservation Act of 1966, as amended, which directs the Secretary of the Interior to develop and make available information concerning historic properties. Guidelines for Evaluating and Nominating Properties that Have Achieved Significance Within the Past Fifty Years was developed under the general editorship of Carol D. Shull, Keeper of the National Register of Historic Places. Beth L. Savage and Sarah Dillard Pope coordinated the publication of the fourth edition of this bulletin. Antoinette J. Lee, historian, Tanya M. Velt, Rama R. Badamo and Mary M. Kell coordinated previous editions.
