I think the book is 2000 Most Challenging And Obscure Words by Norman W. Schur (Galahad Books, NY, 1994). I just picked it up at a swap meet for a buck!
Edit: I see that the book is a compilation in one volume of two previous works by the author.
Well, thank you. But I can't take credit for it entirely...The words are from a book I got at the bargain rack at Barnes & Noble a few years back. One of the best buys I've ever made.
