For two decades, technical communicators have turned to TechWhirl to ask and answer questions about the always-changing world of technical communications, such as tools, skills, career paths, methodologies, and emerging industries. The TechWhirl Archives and magazine, created for, by and about technical writers, offer a wealth of knowledge to everyone with an interest in any aspect of technical communications.
I'll put in my vote for FrameMaker too. I've been using it for a couple of
years (after having rejected Interleaf for many of the reasons others have
already given). I've produced an entire UNIX manual with FrameMaker and
getting all the chapters, cross references, notes, etc. together was fairly
easy. We are moving toward producing all our documents with FrameMaker.
