Being a freelancer you have to be part businessman/woman as well. Thus, I'm looking for books about the business aspect of things such as contracts, copyrights, etc. One book recommended was Graphic Artists Guild Handbook: Pricing & Ethical Guidelines (Graphic Artists Guild Handbook of Pricing and Ethical Guidelines). Are there any others you'd suggest? Would you advise me not to get the Graphic Artists Guild Handbook?
Website recommendations are welcome too. Two useful ones for legal advice that I was told about are:
Volunteer Lawyers for the Arts
Citizens Advice Bureau
