TITLE: Homological Algebra texts
QUESTION [51 upvotes]: I would like to hear the communities' ideas on good Homological Algebra textbooks / references.  The standard example is of course Weibel (which I'll leave for someone else to describe).
As usual, the rule is one reference per post.  Please include some description which distinguishes it from other texts.

REPLY [4 votes]: Appendix 3 of Eisenbud's "Commutative Algebra" is the best short treatment I know. I find it fantastic. It clearly and concisely covers a surprising number of topics in homological algebra.
