[Zope] Good books after 'The Zope Book' & 'Web App Dev + Content Mgmt'?

Hi, I read both, and actually found the Zope Book a better introduction, especially the in-development online version. The Zope Bible seems pretty good, but would someone recommend "Zope Developer's Handbook", "Zope Web Application Construction Kit", and "The Book of Zope"? The last one doesn't seem very good, though. Thx Fred.
