I consider this dictionary a real tool for the study of the Old Testament words. I think it is better and more updated than the "Gesenius' Hebrew-Chaldee Lexicon of the O.T." and more handy with bigger letters than the classic "The New Brown-Driver-Briggs-Gesenius Hebrew-Aramaic-English Lexicon". I think the book is directed to the novice as well as to the scholar student of the Bible. It is a pity that is not so much known as many other Hebrew dictionaries. Perhaps it lacks somewhat of the apparent and refined scholarship of other dictionaries, but personally I prefer its simple, concise and direct analysis of the entries it uses.
An observation addressed to Amazon: Why is it so difficult to find this book by searching it by its title inside the site of amazon.com?
