It is difficult for me to imagine its utility as a desk reference, but it is certainly just as rich and unusual a piece of literature as its reputation suggests.

Hofstadter's 2007 book "I Am A Strange Loop" develops one of GEB's themes in more depth. It's written in a more straightforward style than GEB, so it's less remarkable as a reading experience, but its perspective has stuck with me in a pretty fundamental way, so I would recommend it to anyone who enjoyed GEB and wants to dig further into the puzzle of consciousness.
