I was impressed with these books (set of 3 volumes) the very first time I saw them.
The introduction in the first book brings a beginner up to speed on what is really happening 'out there'. For beginners and seasoned amateurs alike, it helps you to appreciate the objects in the universe, their sizes, the scale of the universe, and our place in it. They help a person to answer the question, "What do I look for?". The long introduction is both a fine tutorial, and a great review, to help one get and keep 'the big picture' in mind.
The books inculde a massive amount of detailed information on objects in every constellation. They earn their own way to a place in my library.
