Thanks everyone for all the good information.
Here's what I've learned:
1. Framemaker 7.0: Classroom in a Book is an excellent resource,
regardless of what the reviews on Amazon says.
2. O'Keefe's book, Publishing Fundamentals: Framemaker 7.0
(previously known as Framemaker 7.0: The Complete Reference) is also
an excellent resource. It's available through www.scriptorium.com as
a PDF, and there are plans in the works to publish an upated version
for Framemaker 8.0.
3. Scriptorium publishes a number of books about Framemaker, and they
offer training courses also.
(All of this is for posterity -- for someone searching the archives --
hope it help!)
Thanks everyone for your information and advice. I like Art's
especially -- read it all and every nugget puts you ahead!
