I stumbled across this book whilst searching for the original record for the snake Enhydris punctata. Confusingly, the Catalogue of Life lists this snake as Enhydris punctata GRAY 1849, implying that Gray's original name still stands, whereas in fact it should be Enhydris punctata (Gray, 1849) as the Gray's original name for the snake was Phytolopsis punctata. It's little things like this that drive me nuts, especially as the Catalogue of Life has no obvious, quick means of fixing this (Wiki, anyone?).
I was also interested in using the OCLC numbers a GUID for the book, but there are several to choose from (including two related to the Google Book). Unlike DOIs, a book may have multiple OCLCs (sigh). Still, it's a GUID, and it's resolvable, so it's a start. Hence, one could link GUIDs for the names published in this book to the book itself.
