As with many pulp magazines of the early to mid-twentieth century, the publication history of The Scrap Book is convoluted. In the early 1900's, Frank Munsey launched three new monthly pulp magazines in consecutive years - All-Story Magazine in 1905, The Scrap Book in 1906, which split into two sections in July 1907 (of which the second was devoted primarily to fiction) and The Ocean in 1907.
The Ocean was renamed The Live Wire in February 1908) and absorbed into The Scrap Book which, at the same time, spun off its second section as a separate magazine called The Cavalier. The first section continued under the name of The Scrap Book for another four years until it was absorbed into The Cavalier, which then went weekly as Cavalier Weekly. This lasted until May 1914 when it merged with All-Story Weekly to form All-Story-Cavalier Weekly.
