Since I bought this book, I have thrown its predecessor dictionary away. The previous one was slightly cheaper and included, oddly, lots of basic law terms (which one would understand anyway) and omitted the more arcane ones (which were the reason for buying the book in the 1st place). Simple test for a dictionary: remember the last few legal terms with which you were unfamiliar, go into the nearest bookshop and look them up. This book is excellent for its coverage of Latin and Norman French 'legalese' as well as terms that have fallen into disuse many centuries ago (save for in the language used by certain Law Lords until recently!) This is by far the best legal dictionary that you will find - and is worth the investment as, sadly, despite Lord Woolf's attempts, latin phrases still curry favour!
