A generalized étale cohomology theory is a cohomology theory which
is represented by a presheaf of spectra on some étale site. Étale
K-theory is the most prominent example.
This monograph gives modern proofs of Thomason's étale cohomological
descent theorem for Bott periodic K-theory and the Nisnevich descent
theorem, and discusses the portions of the homotopy theory of
presheaves of spectra which are necessary to effect these proofs.
The presheaf-theoretic approach to the Lichtenbaum-Quillen conjecture
is also discussed.
Other items of particular interest appearing here include an
elementary description of the theory of smash products of presheaves
of spectra, and a thorough discussion of generalized Galois cohomology
theories arising from the homotopy theory of presheaves of spectra on
the site of finite discrete G-sets for an arbitrary profinite group G.

They comprised a version of
the manuscript that was completed in late 1993; the published version
has been substantially revised.
