I've owned about a half dozen crossword dictionaries over the years. Most I just selected based on price. (The cheapest that is). This Random House edition is not only very reasonably priced, but the very best I have come across as well in a softcover. If you have never seen or owned a crossword dictionary, you should know that they differ from regular dictionaries in that they offer little in the way of meaning, only synonyms of words. (The actually meaning being pretty much able to be deduced from that alone in most cases). They offer the word or clue in bold and then follow it up with as many synonyms that seem reasonable, or the editors could think of. Even if the correct word is not listed, it still aides you in sending you in the right direction as to the clue words meaning. This book also carries a healthy amount of trivia style data for those clues that ask something specific about movies, famous people, locations, political figures, cities of the world, events, etc. Personally I feel it is by far the most comprehensive reference of its kind anywhere near its price. And I highly recommend it.
One last thing, one problem that I have found with a lot of these books is the print being either too small, or the clue word not being bold enough to see and scan effectively. Sometimes the clue word is barely bigger or bolder than the synonyms that follow and it takes longer to find what your looking for. And other times the print is just to darn small for those of us whose eyes have seen better days. The Random House book has both very bold and clear clue words, and the print is a reasonable size. All 'round the very best of the lot in this price range in my opinion...
