Query: The best available for basic legal reference

This twelve volume set is unmatched for many different types of libraries. It is a little too basic for a law firm library, but for academic or public libraries it cannot be beat. It is simply organized, has very thorough explanations of over 4,000 legal terms and important legal events, and devotes a whole volume to a very useful dictionary.
