I bought this book to inform an essay for my english degree, looking into words used in and originating from science-fiction writing, and it was hugely useful, and -if you are into that kind of thing- hugely interesting!
However, there is little in it that is not included in the Oxford English Dictionary as a whole, particularly the online version which is currently (and practically always) being updated, so if you have access to that - not cheap! - then you don't need this book.
The advantages it does have over the OED is that it does collect all these words together without you needing to search through an entire database, and it does have a few dates which need antedating in the OED.
