I'm somewhat torn between the first version, that lists Michael Whelan but not Tom Doherty, and the second version, that lists Tom Doherty but not Michael Whelan. I really don't like the third or fourth versions which capitalize Musician but don't capitalize author or publisher. I'm poor enough at punctuation that I really can't comment on such things as the use of colon, semicolon, and commas (serial or otherwise).
