The 1955 version of The Ghost in the Gallery has 209 pages and 25 chapters. The 1975 version has 180 pages and 20 chapters. The two books definitely tell the same story, and the main difference appears to be that the text has been rewritten and condensed for the 1975 version.
Jean took the other two letters from the mailbox. One was addressed to her, the other to Louise. She knew from the handwriting that the letters were from Ken and Chris. Probably an explanation of the boys’ strange actions about the Saturday night dance.Revised 1975 text:
A moment later Jean exclaimed unbelievingly, "Louise, listen to this! Chris was informed that the dance had been called off!"
The letter to Louise said practically the same thing as Jean’s, that they were told the school dance had been called off. Someone deliberately had played a mean joke on the Danas!
The following afternoon, when the girls returned to their suite to prepare for the dance, they found a telephone message on Jean’s desk. It read:The two versions have approximately the same number of words, but the character count has been greatly reduced. The first version has 561 characters while the second version has 494 characters.
Ken Scott and Chris Barton called to say they are sorry to miss the dance tonight. They hope to be invited next month.
Stunned by the message from the boys, Louise and Jean flopped on the couch in their study.
"This means we can’t go to the dance!" Jean wailed.
Louise thought, What could have happened to make Ken and Chris change their minds?
The Ghost in the Gallery is the only Dana Girls book that had a significant revision, because it was the only one that was reduced from 25 chapters to 20 chapters. The remaining titles all had extremely minor edits which were mainly made to improve the continuity since the order of the titles was changed for the second set.
Using The Clue of the Stone Tiger as an example, opening the 1963 and 1972 versions to any random page shows the text beginning with the same word at the top of the page and ending with the same word at the bottom. Likely, a few minor edits were made scattered through the texts, but the page count and content of each page remained identical.
The first page of each book begins with the same two paragraphs. The books differ slightly in the third paragraph.
1963 version, first page, third paragraph:
The three Danas, en route home to Oak Falls from a long trip, were in a Chicago hotel room. They had just delivered a valuable German shepherd dog, Baron von Neckar, to its owner who had come to the city from New York on business. The two sisters and their aunt had planned to stay for a little sightseeing.1972 version, first page, third paragraph:
The three Danas, en route home to Oak Falls from a long trip, were in a Chicago hotel room. The two sisters and their aunt had planned to stay for some sightseeing, but this latest news made them wonder if perhaps they should go directly home. They had been away for some time on a Western trip.The paragraphs have been changed, but they take up exactly the same amount of space on the page. Some words here and there have also been changed. In the 1963 version, Cora Appel is a "timid, rather harebrained young woman," while in the 1972 version, she is a "timid but faithful young woman."
The revisions are very minor in this book. I have compared some other Dana Girls books that had minor revisions and made the same observations. Readers of either version will enjoy exactly the same story and notice nothing. Only a careful comparison shows that some revisions were made.
