“A library is a collection of books kept for use.” That axiom is key to this sly little book, part of Sternberg’s White Pocketbook Series. Even the title is sly: the “portable document format” refers both to texts assembled in the “library” at dextersinister.org, and to this other amazing artifact of technology, a pocket-sized, hardcover book. Includes 13 texts by a variety of writers (ever heard of that Poe fellow?) that investigate contemporary publishing in its broadest sense, stemming from a New York basement workshop and bookstore in 2006. The second part consists of reproductions of a series of 10 images titled W.A.S.T.E. Proof Prints, with their extended captions.
