In its Standards of Professional Practice the AIGA makes this unequivocal statement regarding authorship, “When not the sole author of a design, it is incumbent upon a professional designer to clearly identify his or her specific responsibilities or involvement with the design. Examples of such work may not be used for publicity, display or portfolio samples without clear identification of precise areas of authorship.” Unfortunately, this dictum has not led to consistency in the way graphic design is credited in magazines, books, websites, or contests and doesn't address the problem of unattributed work.
