I have the adamantium collection. Enormous book, extremely well built even though it is unwieldy. Old style Omni paper stock in a coffee table sized book, 700 pages collecting various wolverine stories, such as his origin, first appearance and things of that nature. Almost like a sampler, but for the most part it does have complete stories to tell. They do, however, all seem to try to shoehorn in newer stories to push their new line of books from what I have seen. So in a book where there is mostly "classic" tales they throw in wolverine and the x men which some might argue doesn't belong. I think for Avengers they have a bendis story in there.
