Newbie bookshelf question

Hi. I just joined this group after seeing in on someone's groups after bouncing around my tagmirror. Fun stuff!

Anyway, we are rearranging our house and I plan to have a spare bedroom set up as the primary library of the house. Do any of you have bookshelf recommendations?

The last time I was at the public library I saw a unit with slightly tilted shelves. Has anyone used that kind at home? I'm also thinking of a double sided unit in the middle of the room.

Thanks for any input!

The dining room is the library in my house. I used bookshelfs from Ikea. They are relatively inexpensive. The shelves can be used on both sides. It is the Expedit bookcase series. Check it out.

That sounds useful, I will investigate too. (Although, having said that, we will probably just accumulate shelves via Freecycle and charity shops on cost grounds, but it will be worth looking at.)
