"This handsomely designed manual—which, by the way, is decidedly not a training manual for projectionists: you need to be a projectionist before you can become an advanced projectionist—will prove indispensable for any organisation presenting old film and, indeed, anything other than the latest release, such is the fluidity of cinema technology."—David Walsh, Journal of Film Preservation
