The Master Key System: which edition to buy
Charles F. Haanel wrote The Master Key System as a 24-week correspondence course in 1912 and published it in book form in 1916. It is in the public domain, which is why so many publishers reprint it.

How to choose
The text of the 24 lessons is the same in every complete edition. Editions differ mainly in print quality and in whether they keep the questions and answers Haanel attached to each part.
For working through the course week by week, a large-format paperback with room for notes is the practical choice; for a copy that lasts, choose a hardcover.
Avoid editions billed as abridged or simplified: they drop the exercises, and the exercises are the point of the course.
