Delay to Amazon?
What's anybody's experience with the time for a book to appear on Amazon?
I published a book with Lulu in the middle of July, but it's still not appeared anywhere but here and Google books. Of course things take some time, but this does seem a bit excessive - a previous book (through a conventional academic publisher) was up within about week.
