The Zope Book, written by the experts who developed Zope, is a guide to building dynamic Web applications using Zope. Authors Amos Latteier and Michel Pelletier teach you how to utilize Zope to write Web pages, program Web scripts, use databases, manage dynamic content, perform collaborative Web development tasks, plus much more.
Whether you are new to Zope or are a skilled user, this current and comprehensive reference is designed to introduce you to Zope and its uses and teaches you how it differs from other Web application servers. From installation and advanced features, such as ZClasses, to using Zope with relational databases, or scripting with Perl and Python, The Zope Book provides the instruction you need.
The semi-official handbook (or rather, intro text).
It is downloadable from the web in a newer edition, but sometimes it is nicer to have a real book, I think. It is a decent intro text, with some detail about programming Zope, but is unfortunately a bit dated. OK as a first book though.
