Jonah:

Wipe that smile off your face. You have not plumbed the darkest

depths of Book Hell until you have set about trying to find out who

owns reproduction rights to the photographs you want to include.

(This particular annex of Hell is named “Permissions Hell.”)

This has only got worse with the rise of the Internet, where nobody

attributes or acknowledges anything. Now you see a cute photogrpah on

the web, decide to use it in your book, and set about trying to find

out who owns the copyright. Lots of luck.
