At least now you can get a copy through interlibrary loan and make copies of the relevant pages until you can find a copy at a reasonable price. But it cost $70 when it was still in print, and it's a superb reference book, so it probably won't get a whole lot cheaper. Keep an eye on Bookfinder.com and Amazon, sometimes they have good deals. Problem is, once someone sees it listed for $140, they're probably going to price theirs somewhere around that, too.
