I think what Jan-Martin has is the old LF Experimenters Sourcebook which is
a comb bound compilation with a blue cover, of copies of articles published
before 1995. In fact I think there were two editions of the "Sourcebook".
The book Dick is refering to is a later glossy bound printed book (pub 2001)
which is much more up to date with current projects., including Dave's Amp.
LF is moving so fast that we will be needing an update of that book soon !!
