I am intrigued by the copyright notice: "A single copy may be downloaded and read but not printed or distributed in any manner without express written permission."<p>I'm not sure what that even means for a document these days. I can't remember the last time I printed something other than an official document (e.g. passport application) so I'm safe about that. Linking to it must be fine; that's no different from telling a friend (various European publishers notwithstanding). But downloading it makes all sorts of temporary copies these days; does this mean I can't open two tabs on the same document? I have a proxy for all http{,s} connections; it and my browser have caches so have I violated this notice?
