Query: A good book, but best supplimented with another

This book is a good reference grammar, and very good for the student of Classical Japanese. However the Japanese vocabulary in the book is not explained well, and it is all in romaji. I would recommend anyone who buys this book to buy a good grammar or dictionary with it. Such as the newClassical Japanese: A GrammarandClassical Japanese Reader and Essential Dictionarybooks.
