We charge a "Permissions Fee" for use of photographs in books, articles,
CDROM, Videos etc.  The fee is charged to "For Profit" entities...is there a
way to request some sort of "proof" from the requestor that they are indeed a
non-profit entity?  What about the Federal ID/Tax#...or is that just for
places that don't get taxed?  I know this may sound stupid, but figured I'd
post it out there anyway.
