There are documented errors in that book, so I for one would be more likely to consider the newest version (which I have access to) that incorporates corrections as reliable than the one on Google Books. AFAIK, there were errata sheets included in the print volume that likely were not scanned.  It might be a good idea to verify those entries, but I as yet have no idea how to cite an e-book page, because I think they aren't always one-to-one with the printed volume.
