Query: Not a book for a beginner

While Mr. Bennett clearly qualifies as as authority in celestial navigation, this book is not well suited for beginners. The narrative is a bit to succint, forcing the reader to try and and "fill in the blanks" in order to understand what the author has stated. Modern publishing makes it easier to present tables and examples with the narrative; however, in this book the tables and examples are at the rear of the book, which makes switching back and forth difficult. The main advantage of this book are the tables. In my opinion this is a good resource book and a celestial navigation reference guide, but not as your first celestial navigation primer.
