I was talking to Pharos today, and he mentioned something that I've been mulling over for a while now in the back of my mind but never took the time to say: We at Wikibooks have a problem with our nomenclature.
Things were easy when we were just an e-book site, because we could extend the "book" metaphor to our creations with ease. A book is broken into little chunks which could be equally referred to as "chapters" or "pages". Wiki wasn't paper, after all, so it didn't matter if one of our "pages" was far longer then a single printed page would be coming out of your printer. The point was moot.
Things are a little bit different now though, because Wiki can indeed become paper in a very real way. All of a sudden we have an insurmountable wall of dense terminology where every word seems to have multiple meanings. Keep in mind that every "book" on our site has two possible incarnations: the on-wiki version and the printed PediaPress version (and even the downloadable PDF version, but let's ignore that for now).
With these two incarnations in mind, what do the words "book", "chapter", "page", "section", "unit", "module", and "heading" mean? If we keep up the metaphor and say the things on our website are "books", then what are those things that PediaPress are printing? A "page" on wiki takes up multiple "pages" in the printed book. A "chapter" in the book is made up of multiple chunks of stuff that we used to call "chapters" on the wiki. In short, we have a terminology nightmare on our hands, and as a result our best tutorials about the subject have descended into opaque and indecipherable jibberish where words are used in multiple different ways, often in a single paragraph or sentence.
And don't even get me started on the difficulty in trying to file bug reports with the PediaPress people, trying to explain how certain "features" in a published book correspond to wikitext syntax in certain places on the wiki. The fact that we've had any meaningful discussions with them is a testament to the sheer courtesy, patience and willpower that the wonderful PediaPress developers have shown. If it's this hard for us to do, I can't even imagine how confused our poor new users are becoming by this all.
