Hey all.

One of the books which keeps being mentioned intermittently is the
voluminous /International Reference Guide to Space Launch Systems/;
currently in its third (1999) edition. I've encountered a moderately
priced s/h copy of the second edition (1995), which is enticing me;
after some checking, I found a couple of interesting details.

The second edition is listed as 341pp.; the third as 350pp.. Now, whilst
I know launch-vehicle development is a little slower than, eg, private
car marketing g, three percent growth does seem a little, well, light
for four years, and leads me to wonder if the third edition trimmed
anything which was previously included - anyone with a decent memory or
a decent bookshelf care to comment?

The other questions are, of course - is the second edition worth buying,
or should I hold out until I can get cash for the third; and is a fourth
in the works?
