The Encyclopedia of Mormonism is an amazing work, in my opinion. It was published 16 years ago by Macmillan Publishers. The writers and editors did a fantastic job on the articles--it's very comprehensive, the articles are very accurate statements of church policy & doctrine, and they are very well-written.

And I just found out that the entire text is available for free online, in pdf format:
