The Emacs GC is a fairly ordinary mark/sweep GC.  I'd say it is nearly
the most straightforward garbage collector you could imagine; or at
least started that way before features like weak hash maps and
finalizers were added :)

It is vaguely similar to the Boehm GC.  The Boehm GC is best known for
doing conservative marking (but it has several modes and isn't limited
to this); whereas the Emacs GC conservatively marks the stack but not
the heap.

If you want to learn more about the Emacs GC in particular, alloc.c is
not that hard to read.  Start with the function garbage_collect_1.

If you need some background in garbage collection in general, the Jones
& Lins book "Garbage Collection" is very good.
