Excellent! Yet another opportunity for me to sing the praises of my beloved seven volume hardback edition, published by Harper Collins (UK) in 1999.
Each book is beautifully bound and so much easier to handle than the three-volume version. The appendixes get their own volume. And it came with a free CD of Tolkien reading his works.
I'd love to post a link to a picture of it but I can't find any trace of it on the net...
