This is a graduatelevel guide to loop quantum
gravity. I hope this will help the reader find
the "prerequisites" as well as some of the more contemporary work on
this approach to quantum gravity. Suggestions are welcome.
You're encouraged not to read linearly (this is, afterall, a
nonlinear field!) For instance, you might start with the more recent
book, "Quantum Gravity" by Carlo Rovelli, which covers most of these
topics, or the older book of Abhay's
("Lectures..."  the little blue book), or the shorter, more
inspirational, reviews and primers and then
backtrack to pick up the background you find you need.
Be aware that the field has evolved greatly since the mid1990's! I have retained older works, since they occasionally come in handy. I will (hopefully soon) include sections on the areas of spin foams and loop quantum cosmology.
Enjoy!
