Jim Watts noted an exhibit by Brian Dettmer a few years ago. Dettmer seems to be continuing his book art work in some fascinating ways, as see in the images here.
Dettmer is also noted in the following book, which I don't think this has been noted in these pages, but this looks worth checking out (especially considering the subtitle):
Iconic books are texts revered as objects of power rather than just as words of instruction, information, or insight. In religious and secular rituals around the globe, people carry, show, wave, touch and kiss books and other texts, as well as read them. This blog chronicles such events and activities. (For more about iconic books, see the links to the Iconic Books Project at left.)
