From the Crockett Johnson homepage: "From just before the arrival of Gorgon (an episode found in Barnaby) to the visit with Rover (in Barnaby and Mr. O'Malley), this volume delivers stories from the two books published in the 1940s. But, since it reprints the original PM strips unedited, we are treated to adventures never before published in book form - such as Barnaby and Jane (and O'Malley) at Mrs. Krump's Kiddie Kamp. Also, there are some subtle textual and narrative variants: in Barnaby and Mr. O'Malley, Gus writes O'Malley's campaign biography; however, in Barnaby #2, it's foiling the "Hot Coffee Ring" that prompts O'Malley to want his biography written."
