I could not have made these games without some truly excellent resources. You can find the Amazon links to the books I used below, but all of these books can be found at your library. The resource I used the most, in fact, The Oxford English Dictionary Online (OED.com), I accessed through my library’s internet portal. Private OED access is expensive, but chances are your library has purchased a membership. If you’ve got a library card, then you have free, unlimited access to the most comprehensive dictionary in the world. Ask your local reference librarian – he or she will be delighted to help you, because librarians are awesome and granting you access to the knowledge of the ages is their dutiful pleasure.
Christine Ammer’s American Heritage Dictionary of Idioms was essential for Village Idiom I – it contains the most succinct, comprehensive, and up-to-date research on idioms that I have yet found.
Edith Hamilton’s Mythology is perhaps a little dated, but heck – it’s about ancient Greek mythology. Nothing has changed about Greek myth since the dissolution of the Delian League, 2400 years ago.
I also used Thomas Bulfinch’s Greek and Roman Mythology, which filled in gaps left by Hamilton’s Mythology.
For everything else, and I do mean everything else, I used the New York Times Guide to Essential Knowledge – this volume is an encyclopedia of esoteric knowledge. It’s not a normal encyclopedia – it has rather lengthy essays on a small but diverse body of subjects, as opposed to great breadth and limited depth. Although I suppose you could have both breadth and depth if you wanted to spring for all 30 volumes of the Encyclopedia Britannica, if you fancy the notion of owning an encyclopedia collection that compares in weight to a full-grown Great Dane.
