Right now, my books are arranged according to author, regardless of genre. My brother, my Mom, and The Boyfriend frequently borrows books from my shelf and they said that it's easier for them to find books through that system. But every few weeks or so, I rearrange my shelf to reflect my current mood, or whatever I thought would work. I sometimes arranged it according to size, favorites, color, genre, from awesomesauce to fugly books, etc. I love rearranging my books!
This is the best book shelf accessory, in my opinion. This snow globe was given to me by a really awesome friend of mine, who also loves reading books:
So there you have it, my pink book shelf and my obsession with rearranging my shelves.
