BOOK CREDITS -- logo and credits box
CC0 1.0 UNIVERSAL / PUBLIC DOMAIN DEDICATION

To the extent possible under law, the author has waived all copyright and
related or neighbouring rights to the BOOK CREDITS logo, the credits box, and
every file in this pack. You may copy, modify, distribute and use them, in any
medium, for any purpose, commercial or not, WITHOUT PERMISSION AND WITHOUT
ATTRIBUTION.

This is deliberate. A disclosure standard that you have to ask permission to use
is not a standard. The whole point is that any author, any publisher and any
printer can put these credits in a book without contacting anybody.

You do not need a licence. You do not need to credit bookcredits.org. You do not
need to tell us. Use it.

The only thing asked, and it is asked rather than required: if you display the
BOOK CREDITS mark, publish the credits honestly. The mark means the credits are
there and complete, and it is worth nothing if it is used where they are not.
