For Dick's paper, see:

The idea is clear from the block diagram, if you don't want to read 
the whole paper:

Oliver Collins published a paper expanding on this idea ("The Design 
of Low Jitter Hard Limiters," 1996).

I concur with Rick's suggestions.  I would also suggest Edson's 1953 
text, "Vacuum-Tube Oscillators," which gives details on some concepts 
that are often glossed over in later texts:
