I also really like books. Some time I will write a bit about my experiences as a (online) bookseller. A lot of the attraction was having all these books. At my peak, I had more than you do. When I dumped the business I cut back to a reasonable number (and they aren't in inventory anymore, so I can't tell you how many I have.)

Personally, though, I'd rather spend time reading the books than rebinding them so they look nicer.

but yeah, I can understand the want to collect books, even books that you likely won't have time to read. But, I mean, if it's not something you are likely to read, it's more of a collectible or decoration than a book, especially if you are going to put a lot of labor into making them look good, which is why I say it sounds like a display of wealth.
