Land and Environmental Art
Jeffry Kastner and Brian Wallis

Another big book on a big subject, this one surveys the work of over one hundred practitioners of the field, with interviews, images, reprints of essays, articles, and then some original thoughts. Much of the images and text is familiar (Smithson, Heizer, Long, Holt, De Maria...), yet this is one of the broadest nets yet cast around the subject, with some new additions to the canon.
