Thanks to a post from Eric Rosendale that pointed me to this: http://www.teachermagazine.org/tm/toc/2007/10/25/index.html, The Teacher Professional Development Sourcebook. It's online now. You need only register on the site. Both are free.
Lots of good reading here. Too much for me to type at this hour as I try to rush out the door.
