Here is an hour-long talk by Spector sponsored by the New York Center for Book Art.
At 6 minutes in, there is a wonderful riff on the book as elemental cultural artifact, being able to stand for each of the four elements. Here are links to the images to which Spector refers – so much more enjoyable to see as well as hear!

There is a related brief note about Spector’s “The Rise and Fall of Books” here. Spector’s works — especially his collages with found poems drawn from book jackets — strike deeply. With them, book art goes beyond the read artifact into the relationship of writing and reading.
