Harrison's Reports was a New York City–based motion picture trade journal published weekly from 1919 to 1962. The typical issue was four letter-size pages sent to subscribers under a second-class mail permit. Its founder, editor and publisher was P. S. Harrison (1880–1966), who previously had been a reviewer for Motion Picture News, in which his column was titled "Harrison's Exhibitor Reviews".
The first issue, dated 5 July 1919, stated that film advertising would not be accepted. A year's subscription cost $10. For more than a year, the type was set by a typewriter. The issue of 4 December 1920 and all subsequent issues were professionally typeset. The masthead of 1 January 1921 proclaimed itself
FREE FROM THE INFLUENCE OF ADVERTISING
In later years, that slogan was changed to
A REVIEWING SERVICE FREE FROM THE INFLUENCE OF FILM ADVERTISING
During its 44 calendar years of operation, more than 2,200 issues of Harrison's Reports were published. Approximately 17,000 feature films were reviewed; shorts were not reviewed, although their titles were listed in the indexes published several times a year.
