Thank you for the comments and links for latex and docbook. Going the latex path seems to me worthwhile - but on another day ;-) , I have already done some setup in zope that I would like to build on. What I did not find about LaTeX was a screenshot (isn't it a wysiwg enviroment on top of TeX marked-up text) and a content link to zope - this might be done, however, through the DocBook DTD and the XML stuff in zope. Which leads me to the later suggestion, I have tried out DocBook product, rendering is very slow on my computer. And again it is too big of a new concept for me now. I have looked into the YihawDirectory product a little deeper now, it fits very well into my idea to connect the content with the references closely. A lot of my code methods I produced in order to tweak a good reference handling is not needed any more, what is left are a few headers and footers implemented as methods, for design and navigation purposes, and folders having chapter properties and containing documents for holding content. I still want to look into XML and DocBook, though, xml could be easier to manage as the work grows. On first glance, for xml I found an interesting (but somehow abandoned) software named conglomerate http//www.conglomerate.org/, another is Xeena of IBM. The GUI of both (especially the former) seem to have nice XML editing capabilities. Christian
