THE HARDY BOYS ONLINE: An unofficial online resource for fans of the Hardy Boys books

Hardy Boys Canon

The "Canon" refers to the 58 volumes published by Grosset and Dunlap from 1927 to 1978, as well as the Detective Handbook. For many collectors, these are the "true" Hardy Boys books. In any case, their long history means that there's a lot to say about them! A detailed booklist, with cover art, is shown below, and I've divided the rest of the information into the following parts:

  • History - from the beginnings in the 1920s to the end in the 1970s.
  • Revisions - a timeline of the revisions, an overview of the types of revisions that were carried out, and a list of ghostwriters.
  • Interior art - information about the black-and-white interior illustrations.
  • Cover art - a list of cover artists and a timeline that charts the date when each new cover appeared.
  • Front cover design - classification and discussion of the graphic design of the covers.
  • Spine design - description of the various spine colours and designs.
  • Back cover design - description of the back cover designs.
  • Endpapers - scans of the endpapers (the inside front and back covers) and a key to the scenes they depict.
  • Interior formatting - layout of title page, contents, headings; fonts used.
