"Correct style should hold those minor pages into the overall Paul Harris biography page." -- please explain: what makes this style "correct" apart from the fact that it is closer to a print encyclopedia? If I was researching "magic books", I would prefer a page called "Books by XXX", which was linked to the bio of XXX rather than having to wade through every bio to find book information. Please reconsider this imposition of questionable style.
Separate Or Equal?
It's not a rule by any means.
I do see your point of seeking "magic books," but by your logic someone seeking "magic books" will still have to go through every "Books by XXX Magician."
My idea is that if someone researches "card magic" they should get entries including those magicians who do card magic and find through those biographies the published works of that magician.
If you browse the structure that currently exists on MagicPedia, someone seeking "magic books" can go through Close Up Magic to Close Up Magic Books. From there, they have books indexed by author, publisher, title, artist, and potentially date. As the wiki grows organically, all natural cross-references will be added. Someone seeking "magic books" need not go through every "Books by XXX"...
Of course, your idea that 'if someone researches "card magic" they should get entries including those magicians who do card magic and find through those biographies the published works of that magician.' is very reasonable. However, this structure need not preclude additional structure. The very best and most useful wikis are not those that copy wikipedia, but rather are those whose structure is as much a community project as its content. Imposing style and structure constraints at this stage in the game is stifling.
Incidentally, attempts to edit the Paul Harris page now include the "WARNING: This page is 45 kilobytes long; some browsers may have problems editing pages approaching or longer than 32kb. Please consider breaking the page into smaller sections." ...
I agree about the length and will restore the separate pages (books and tricks).
I can see the logic, but at least hope that these pages (and for all future pages like this) keep very well interlinked.
