Here's a collection of varied texts which don't fit into any of the other categories I've set up, but are worth the time IMHO.

The Complete Rhyming Dictionary, Clement Wood, Editor (Hardcover). If even Stephen Sondheim uses a rhyming dictionary for his work, anyone who works on poetry or lyrics should do the same. He prefers this one because of its unique format. Also available in paperback, but I believe reference texts should be bought in hardcover as they will get much wear.

The New York Public Library Desk Reference, The dustjacket describes it as "The ultimate one-volume collection of the most frequently sought information. An exhaustive collection of reference material in one source."

I Love Me, Vol. 1: S. Wordrow's Palindrome Encyclopedia by Michael Donner (Introduction) Read the title backwards. Palindromes rear the same in both directions. Like racecar.

Macintosh Computers:

Insanely Great : The Life and Times of Macintosh, the Computer That Changed Everything Steven Levy (paperback) How many computers get their own lifestory? Sondheim uses a Mac and so do I. See the story of the computer that made Bill Gates stop to think about what a real operating system should be like.

The Little iMac Book, Robin C. Williams (paperback) Williams' other books on the Mac and computing have been great helps. This one promises to be the same
