I really enjoyed this article about book hoarders. Some hit home more than others, but they all look wonderful
I remember going on a tour of Hearst castle and wondering how I could get to spend more time in the room with all of the books. I also wanted to spend time in both of the pools, but I found out how I can do that. ($$) I never did find out about the library there.
Since George Lucas is semi near me, I wish that I could spend time browsing his library, too.
All of these people had wonderful collections. I mostly collect paperbacks, but about a third of mine are hardbacks. Nothing expensive. The majority of mine are on Kindle, though. I suppose that counts as a collection of some type, but most people won’t be browsing through there.
