Thought I'd do a bump-up on this one seeing as we've been talking about different editions on the Books forum. Plus, I've got some rather ace links here - which I must add, davem actually found last night.
The Tolkien Library is a site which aims to detail all the writings available by Tolkien; it also has items about collecting the books, and some other good links.
This gallery of Book Covers is fascinating - and not so long ago (though I cannot now recall on which thread) I asked if anyone knew if there was such a thing as a gallery of cover art. Well, there is, and this is a pretty good one as it includes not only popular covers but some strange and freaky ones too.
Finally,
Tolkien Books is my favourite of these three as it's focussed on UK editions and goes into detail with just about anything you might need to know about the many editions available (apart from prices
). I should imagine this would be really useful when browsing ebay... It also has a lot of useful info. I was on this for too long last night, mentally creating a shopping list...
