    There's a chapter (maybe 2) in a book: Inside SQL Server 2005: T-SQL Queries by Itzik Ben-Gan

    Excellent book.

    I'd refer to Itzik's book as well.

    But, while you're waiting for it to arrive, there is some explanation here. Here's a bit more. None of this addresses it directly the way Itzik's book does.
