Readers of this list will be interested in checking out Marshall Rose's
latest tome:
"The Internet Message: Closing the Book with Electronic Mail"
published by Prentice-Hall (ISBN 0-13-092941-7)
It's fun, informative, and opinionated, just as you'd expect from
Marshall, and it has 60 or so pages on MIME, including a monochrome
version of the Telephone Chords picture I sent to this mailing list as a
MIME message last spring. Since that makes it the only published book
in the universe, to my knowledge, with a picture of me singing, it is
clear that everyone needs to buy a copy!
