This volume contains a useful variety of words, phrases, and biography information that you won't find in any other dictionary. While reading newspapers, magazines, and other current media, I often encounter cultural references, phrases, proverbial sayings, and more, that aren't listed in any dictionary that defines single words.
For example, The Oxford Dictionary of Phrase and Fable contains entries for a wide variety of subjects such as John Lennon, Pop goes the weasel, and "It's the economy, stupid." Great stuff!
At well over a thousand pages, this volume has all the heft of any good dictionary.
