Lyle Hugh Munson^[1] (?- c. 1974)^[2] was an intelligence agent^[3] and then, later, a book publisher and distributor under the corporate name Bookmailer, Inc.. Based in the New York area, his company was known particularly for offering anti-communist works.

Robert W. Welch Jr., the head of the John Birch Society, considered him a "good friend".^[4] Munson's advice to the Austrian economist Ludwig von Mises for the author to threaten Yale University Press to take Human Action to another publisher because of delays caused it to rush out its flawed second edition.^[5]

Munson worked for the OSS starting in 1940,^[6] and in the CIA's psychological warfare division. In 1949, he testified before the Senate Internal Security Subcommittee.^[3]

During the 29 years of its existence, Bookmailer published around fifty books on its own,^[2] in addition to distributing books published by small publishers. They were based in New York City, changing offices after an April 18, 1961, burglary.^[7] In 1964, they moved to Linden, New Jersey.^[8][9] The company was 20% owned by P. C. Beezley. Sales circa 1960 were about 200,000 volumes per year,^[1] and grew to around 2 million in 1961 off of a wave of interest in anti-communist material.^[10] Employees included Herbert Romerstein,^[11] later director of the U.S. Information Agency's Office to Counter Soviet Disinformation under the Reagan administration.

According to Russell Kirk, Bookmailer advertising was turned down by conservative journal Modern Age because his advertising agent had a Jewish name.^[12]

Munson and his wife, Anne, moved from New Jersey to Mattoon, Illinois less than a year before his death. After he passed, Anne started her own by-mail bookselling operation, Munson Books.^[2]
