Use a letter like this to resist the bandits:
As you may be aware, your copyright assignment form/letter/contract goes
against the spirit of the 1988 Copyright, Designs and Patents Act.
Freelances like me are only able to trade legally if we retain ownership of
our work. As you will know, it is common practice for writers and
photographers to issue publishers with licenses for their specified
publication needs. Publishers need to make separate arrangements and
additional payments for repeated uses of material or any form of
syndication these rights are not automatic.
I am happy to discuss your needs with respect to my material and appropriate
fees. In the absence of such an agreement I am prepared to offer you a
licence for one use only in [name of publication]. This does not cover
re-use, electronic publication in any form, or syndication.
