The GC-LIST FAQ
A draft FAQ for the Garbage Collection mailing list. Includes a list of algorithms and techniques, related jargon, language interfaces, and challenging problems such as threading, distributed objects, persistency, and "uncooperative environments".

A garbage collector for C/C++ (Hans Boehm)
Hans Boehm's page on the widely used Boehm-Demers-Weiser conservative garbage collector for C/C++. The Boehm-Demers-Weiser conservative garbage collector can be used as a garbage collecting replacement for C malloc or C++ new. It is also used by a number of programming language implementations that use C as intermediate code.
