Hmmmm

Hypothetically, if a writer had to fill 16 pages in the back of a book with "extras"- like DVD extras but for, like, a book- then what should he fill those pages WITH?

An interview? A list of his influences? Deleted/discarded scenes? Something else?

Or maybe you'd just like 16 BLANK pages at the end of a book. You know, for your own doodling and such...
