Query: If nothing else, it looks good on your bookshelf.

You would do better off buying these books individually from a different publisher.It sounds impressive, leather bound, gilded edges, but it is very cheaply done. On the plus side, it does have a ribbon book mark so you don't have to buy your own.But this book was poorly edited, filled with needless typos, and with all four of these books available from numerous other publishers, I would suggest to just buy it from them.
