Can you own too many books?

According to this Toast article, you can:

How many books does a person have to own to officially be labeled a book hoarder? According to Shelfari’s Compulsive Book Hoarders Group, the answer is simple: 1,000 or more.

Being well above this number, I’m obviously resistant to the idea. But I thought that the idea warranted a little more than a “NO! You are!”

My personal rule is that every book I have must either be a) something I really enjoyed, or b) something on my To Be Read list. If I’ve read something and didn’t like it (or even just found it “meh”), it’s got to go. That, to me, is the line – keeping books for the sake of keeping books, not because a particular book has value of some kind.

Even if I won’t read them again, I like having the books I’ve loved around. I like having a friend over for tea and being able to send them home with a loan to read. That has value, and it keeps the behaviour of owning books purposeful rather than being a possible sign of mental illness.

If you have any thoughts on the matter, I’d love to hear them! Am I way off base?
