Nathan Bierma has posted his list of the 10 best books for linguists, word lovers. I couldn't find it online yet, but I will post the whole article (which briefly describes the books) as soon as I can find it.

10. "Proust's English" - by Daniel Karlin

9. "Analysing Sociolinguistic Variation" - by Sali Tagliamonte

8. "Standard Negation" - by Matti Miestamo

7. "British or American English? A Handbook of Word and Grammar Patterns" - by John Algeo

6. "The Quote Verifier: Who Said What, Where, and When" - by Ralph Keyes

5. "The Official Dictionary of Unofficial English: A Crunk Omnibus for Thrillionaires and Bampots for the Ecozoic Age" - by Grant Barrett

4. "Far from the Madding Gerund and Other Dispatches From Language Log" - by Mark Liberman and Geoffrey Pullum

3. "Totally Weird and Wonderful Words" - by Erin McKean

2. "Words, Words, Words" - by David Crystal

1. "Language Variation and Change in the American Midland: A New Look at 'Heartland' English" - edited by Thomas Murray and Beth Lee Simon

He also looks into language books coming out in 2007, and this one sounded interesting to me: "The Unword Dictionary: 1,000 Words for Things You Didn't Know Had Words!" - by Steve Kiehl

Here's the link to the article Kalleh cites.

What, in #6, is "A Crunk Omnibus" and a "bampot"?
