I encourage you to check out this post on book collecting over on Exile Bibliophile. I recently discovered that blog while clicking around the discussions over on LibraryThing. Here’s one of my favorite snippets:

“Not everyone who owns a lot of books is a book collector.  Granted.  I wear pants most days, and own many pairs, yet don’t think of myself as a pants connoisseur.  Book collectors are the same way.  A book collection has a purpose beyond accumulating, beyond, even, reading.  A book collection has a purpose.  What should the focus be?  That’s the beauty of it.”

I like people who group their books in some logical or at least interesting fashion. I REALLY like people who dive deep into a category or genre or author. Those are always great conversationalists. And indeed. That is the beauty of it.
