Nance Van Winckel has gone undercover for Numéro Cinq, searching out and interviewing a series of hybrid or conceptual artists (cross-genre art --- ah, but is there any other kind?). Now she introduces us to the amazing book art of Marilyn R. Rosenberg of Peekskill, NY, who, yes, explodes the concept of book into a phantasmagoria of cutting, folding, sculpting, drawing, image layering, colorizing, painting --- books become sculptures, words become objects, objects become poems, poems become objects AGAIN. We all love books, adore books, but mostly for their efficacy as carriers of words, which, if you follow the logic, leads us all to owning tablet readers; what Marilyn R. Rosenberg creates is the anti-Kindle; you can't read these on a device; she creates unique books, not for dissemination but for themselves for the beauty of the thing.
