Garbage Collection Book

Garbage Collection -- Algorithms for Automatic Dynamic Memory Management, by Richard Jones and Rafael Lins.

A truly one-of-its-kind book; there is no other volume which covers the topic of GarbageCollection so thoroughly.
This book will doubtless grow in importance as languages with GarbageCollection continue to move into the mainstream of computing.
Highly recommended for anyone interested in programming language development or implementation.

You certainly responded enthusiastically once I posted this on ImplementingLisp; I take it you've read it before? :-) -- dm
