Just a quick fyi: If you head over to the Harvard University Press web site, you can grab a free copy of Marcus Boon's new book, In Praise of Copying, which makes the case that "copying is an essential part of being human, that the ability to copy is worthy of celebration, and that, without recognizing how integral copying is to being human, we cannot understand ourselves or the world we live in." Boon is a writer, journalist and Associate Professor in the English Literature department at York University, Toronto. You can download a free copy of his book in PDF format straight from this link. (Note that the text is formally released under a Creative Commons license.) Or you can always purchase a printed copy online.
P.S. The University of Chicago Press is offering up a free e-book of its own: The Bourgeois Virtues (632 pages) by Deirdre N. McCloskey. Head here to get a copy.
