Not mutually exclusive! But each way appeals particularly to a certain inclination of the booklover nature . . .
The Sensualist just loves to have books around: in view, in shelves, in stacks, in bed, in short--everywhere.
The Infomaniac adores books as: founts, repositories, tools, etc., capable of feeding the need to know.
The Reader really wants to get lost in each book, savoring its world and relishing the pure experience of eyes-on-the-page.
If you're a Sensualist, visit this post from The Nonist to see some of the most gorgeous libraries imaginable. (Please pause to admire the search-bait post title.)
Infomaniacs, you'll appreciate Matt Cornell's great post: How to Read a Lot of Books in a Short Time.
For you Readers, of course, the web is rife with possibilities, from Amazon reader reviews and lists to online book clubs to author fan sites to the many-many booklover blogs you can (what's the phrase I'm looking for here?) . . . Stumble Upon!
Whatever your personal persuasion, I hope you'll join me to explore and enjoy all three flavors of book-love. Just add BIBLIOgraphy to your blog reading list.
