It's a minor difference, but while adding the chapter list of the third edition, I noticed that "Author's Notes" differed from the first edition's "Author's Note", and "Introduction" had a comma after it while the first edition list does not. Are these typos to be corrected, or did the first edition list the chapter titles this way? John Gamble ( talk) 19:59, 22 September 2020 (UTC) reply
