There is a followup article, first in the 5-article series *Derived Algebraic Geometry*: * [Stable Infinity Categories](http://arxiv1.library.cornell.edu/abs/math/0608228), arXiv:math/0608228 In particular, > The theory of stable ∞-categories is not really new: most of the results presented here are well-known to experts. There exists a sizable literature on the subject in the setting of stable model categories (see, for example, [27]). The theory of stable model categories is essentially equivalent to the notion of a presentable stable ∞-category, which we discuss in §15.
