Apparently, the author Ford Maddox Ford favoured the idea of judging a book that one might read by reading page 99 first. The logic being that it won’t that it will be a good example of the general standard of writing in the book. An article in the Guardian says that there is a web site starting up on which authors and readers will submit page 99s of novels for public perusal.

Page 99 is a completely arbitrary point at which to test the literary waters, but it is an easy number to remember (if choosing a number is too difficult for the prospective reader). It’s also not too far into most books. The Guardian piece says it will be a quarter to a third of the way through most books – make that a fifth to a tenth of the way through a fantasy novel.
