These days, books, like CDs and adopted children from war-torn nations, are collector's items for those who can afford them. Well, the current exhibit at New York's Center for Book Arts supports that idea anyway. "Artist as Publisher" isn't a gallery of art so much as a gallery of art publications. Skewing towards experimental work, the show examines the role of publications in the lives and careers of artists who have made a name for themselves, initially not through high-profile exhibitions but through independent publication -- an easier and more effective method of disseminating artwork.
