Forum:Discrepancies between the unabridged audiobook and the text

Audiobook vs text

I have been listening to the Unabridged Audiobook by Rob Inglis while reading along with the text and have notices some differences. The text I have is a Balantine Books with a copyright of 1965 and is the sixty-sixth printing in June of 1980 (ISBN 0-345-27259-5). Most of the differences are contractions ("aren't" in the audio while "are not" in the text) and some rearranging of words.

For example, in The Two Towers, Ch 9, Flotsam and Jetsam, ( my p. 217) the text says, "... shadow: it is difficult to see them moving." But is read by Inglis as "...shadow:  it's difficult to see them moving..."

Is this because he is reading from a different version of the text or because he is reading it incorrectly, or with his own "flair"?
