IE Tip 45: American Institute for Graphic Arts (AIGA)

AIGA is the oldest and largest professional membership association for creatives in the design field. Its goal is to inform, communicate, inspire, and validate designers and the design profession. Some really handy resources for freelancers or design entrepreneurs are the "Design Business and Ethics" brochures that are published periodically on topics such as educating clients and recognizing legal requirements faced by design firms. The website also has a sample of a standard agreement for design services that you can customize depending on your design engagement.
