I'm going to pick this up for its research value, if nothing else. Even though I've got everything on that list with the exception of individual GK issues and a few of the old book/record sets -- including stuff that's not there (LA Times strips) -- it'll be nice to have it all in one place.
I can't see myself getting rid of my actual comics/collections/etc. though. I'm too old-school and still love walking into my downstairs library and seeing all that stuff on the shelves.
