The Stratemeyer Syndicate began the text revision programme of the Hardy Boys (as well as other series including Nancy Drew, The Bobbsey Twins, Dana Girls, etc) in 1959. This process involved the cutting, editing and condensing of the original texts, or in some cases writing whole new books that had absolutely no resemblance to the original book of the same title. This process was done to the first 38 titles. One original text and seven revised texts have never been published in a UK edition. The following table lists the publisher who released the original text, followed by that who published the revised text version.
The revised texts can be categorised in four ways:
A = minor editing, cutting, condensing and trimming of text
B = major rewrite but with many recognisable elements from the original
C = major rewrite with very few recognisable elements from the original
D = wholesale rewrite with no resemblance to original whatsoever
