Good introductory books on homological algebra

Which books would you recommend, for self-studying homological algebra, to a beginning graduate (or advanced undergraduate) student who has background in ring theory, modules, basic commutative algebra (some of Atiyah & Macdonald's book) and some (basic) field theory?

I would especially like to hear your opinions on the following books:

A Course On Homological Algebra / P. J Hilton and U. Stambach

Introduction to Homological Algebra / Szen-Tsen Hu

Notes on Homological Algebra / Rotman

But other recommendations will also be appreciated.

Solution 1:

See also A first course of homological algebra by Northcott. There's a list in this review if you have access to MathSciNet.

Solution 2:

See "An introduction to homological algebra" of Rotman (2010). I think this is the book Mark was talking about. It is VERY introductory.
