I'm interested in learning homotopical algebra (by which I mean: model categories, simplicial methods, etc.) However, I've been unable to make heads or tails of any of the "standards" (Jardine&Goerss, Hovey, Hirschorn); they seem to presuppose knowledge of the subject material. What are some accessible introductions to this subject? (+ reading paths to get to the aforementioned "classics"?)

Background: I'm very comfortable with category theory and homological algebra, am learning enriched category theory, and have had a course in algebraic topology (and am currently studying more).

    I found the appendix to "Higher Topos Theory" helpful (as a supplement). Also, another thing you might enjoy, while learning this, is working out (since you've studied homological algebra) the fact that the (unbounded) derived category of $R$-modules is the homotopy category of the category of chain complexes of $R$-modules with the usual model structure. Many of the techniques when working with the derived category are kind of analogous to this model category formalism (e.g. the "derived functors" work out the same). – Akhil Mathew Sep 15 '11 at 02:29
  • Also, I found the article by Goerss on the subject at http://jdc.math.uwo.ca/summerschool/ really fun. One application of the fact (explained in this article) that one can construct model structures on simplicial $R$-algebras for $R$ a commutative ring is the construction of the "cotangent complex": it is a nice concrete example of a (non-abelian!) derived functor. – Akhil Mathew Sep 15 '11 at 02:31

Have you tried to read Hirschhorn, but starting on Part 2? -The first part is the real purpose of the book -localization of model category structures-, but more specialized and advanced. The second part is designed to serve as a support of that, more advanced, first part, and contains all the basics of homotopy theory (model categories). I would try, at least, with chapters 7, 8 and 9 -see what happens: I think it's not intended to be a "pedagogical" book on model categories, but a reference for the results on the first part. Nevertheless it is, first of all, systematic, and secondly, quite readable.

I don't know if it is quite an introductory book but Quillen is not bad at all.

Dwyer and Spalinski is good as well.

There is a section in the Motivic homotopy theory book written by Bjorn Dundas (the section is by Dundas, the whole book is by a few other people as well). This might give the overall picture before you look for something more detailed.
