Alan Bamberger is a San Fransisco-based, self-taught art appraiser and former rare book dealer specialising in fine and decorative arts books, who consults with artists and collectors from all over the world through his much-loved website at artbusiness.com, which has been online since 1998. The site gets 5-6,000 unique visits a day from artists, collectors, wanna-be collectors and the art-curious who can peruse hundreds of pages of his original articles about the art business. With his broad range of art and art business knowledge, and his privileged position as a respected writer and interviewer in the art community, he can give a perspective to art collectors and artists that very few in the art world can. Since the beginning, his site has been financially supported by hundreds of collectors, galleries and art sites through donations. He has two other publications: Buy Art Smart and Art For All.
