On Special:Booksources, I am pointed to places like
Amazon.com by ISBN.
Why not open an account on
Amazon.com for referrals? You can make money,
and the only difference to the user is that the URL clicked on will say
http://www.amazon.com/exec/obidos/ASIN/0140123456/Wikipedia
instead of
http://www.amazon.com/exec/obidos/ASIN/0140123456
Not much of an intrusion, and it would bring in some bucks for Jimbo the
capitalist who runs Wikipedia.
