I agree completely that the Zope Book beta will get more reviewers, and better feedback to the authors, if it is available as PDF. The authors of the "Planning Extreme Programming" book made their draft available as a PDF well in advance of publication and got lots of thoughtful feedback as a result (based on what I saw on the XP email list). Here's a blurb in the "To Reviewers" section at the very beginning: Feel free to pass on this draft to anyone who might read it and comment. We aren't terribly worried that you will use the text in its current form and not buy the book when it comes out. If you do, the mistakes we have deliberately seeded herein will come back to haunt you. Better all around if you just buy the book when it comes out, hey? I printed the draft and now plan to buy the book, now that it's finally out. (I just hope that the book is printed on better paper than the "Extreme Programming Explained" book. Addison-Wesley sure cuts costs on their book paper -- I presume they pass that savings on to us.) -- Fred Yankowski fred@OntoSys.com tel: +1.630.879.1312 Principal Consultant www.OntoSys.com fax: +1.630.879.1370 OntoSys, Inc 38W242 Deerpath Rd, Batavia, IL 60510, USA
