Book two in the Architecture Journal series is now out: Readings in Service Orientation, which you can download from here. Plenty of good stuff to read, though I was surprised to see that several of the included articles are about Software Factories and not quite about Service Orientation per se.

A lot of excellent material brought together, though, and well worth reading all in all.
