In the library, I did a side-by-side comparison of this book (Spears: NTC's Dictionary..., 3rd ed., 2000) with: (a) Green, Jonathon: Cassell Dictionary of Slang, 1998, and (b) Chapman, Robert: Dictionary of American Slang, 3rd ed., 1995. The advantages of this dictionary over the other two are: (1) some words/phrases are in this book but not the other two (e.g., "kipe," "WYSIWYG"); (2) it has more examples of usage in context (usually two per entry); and (3) it is less expensive. On the other hand, this book has: (1) far fewer pages (xv+560) and entries (about 10,000) than the other two books; (2) only a rare indication of when a word/phrase was first in common usage; (3) little info on what sort of people (e.g., "students") originated or might use the word/phrase; (4) a "Phrase-Finder Index" (pp.485-560) whose entries should have been integrated in the body of the dictionary; and (5) wasted space in the "Phrase-Finder Index" when a given word is at the beginning of a phrase (e.g., under "aces" it's good to have "hold all the aces" but worthless to have "ace boom-boom," "ace boon-coon," and "ace in the hole" since these are on pp.2-3). Hey, buy all three from Amazon.com!
