William Dwyer, Philip Hirschhorn, Daniel Kan, Jeff Smith,
Homotopy Limit Functors on
Model Categories and Homotopical Categories
Mathematical Surveys and Monographs 113
AMS 2004
on the theory of homotopical categories and model categories – a presentation of (∞,1)-categories –, their simplicial localization/homotopy categories and derived functors such as homotopy limit functors.
A historically important early manuscript draft of this book is
The draft serves as an original reference for the Kan recognition theorem (in §II.8) and the Kan transfer theorem (in §II.9), as well as cofibrantly generated model categories (in Chapter II). This material did not make it to the book.
Furthermore, this draft originates the modern definition of a model category (in §I.1.2), modifying the original definition of closed model category by Quillen by replacing finite (co)limits with small (co)limits and requiring factorizations to be functorial.
