But we now know what size elephant we have: 1165 pages of elephant, and 235,546 words (according to Word), and that's after the latest cuts. LARGE elephant.
Please note: the bits you won't see are not necessarily worth seeing. Rembrandt's and Michaelangelo's sketches: worth it. Lots of other artists' sketches, not so. Discards are often just plain junk. Verbal chunk, marble junk, paint-on-dirty-canvas junk. We learn by doing it wrong.
The bits that ARE worth seeing, I will try to get out in the open sometime, probably on my website.
