Hardy Classes

There are a few books within a subject of mathematics whichstand out from the others, and this is one. The writing is crisp, and yet engaged. It is also the place where we look up the fundamentals in the subject;-- and it is one which seems to be timeless,-- one that doesn't go out of fashion. As the fashions change, we still need to be able to refer tothe fundamental and timeless ideas, upon which the changing trends continue to rely. It is great that we have Dover toreprint such classics in math. Even among the classics, this one is special.
