This new reference work draws on Oxford's unrivaled bank of online language resources to provide a wealth of fascinating and informative background detail for over 10,000 phrases and allusions used in English today. Among this plenitude are entries on African Eve, Blair Babes, Custer's Last Stand, friend of Dorothy, ground zero, Oradour, Red Queen hypothesis, shoot the messenger, and Trojan horse.
Okay, so I haven't read this... It is a reference book. I do want it on my bookshelves, though. I plan to use it later and don't want to forget about it. There is a copy at the HBLL.
