This week's bookcase comes to us courtesy of London-based architecture firm Gianni Botsford. 

I love how books are just stuffed up to the ceiling and how those diagonal lines make the shelving a bit more interesting. There's another shot of the room showing all the shelving (yes, there's more) after the jump.

[I've had a lot of people ask me where last Wednesday's tree bookcase is from. It's by artist Shawn Soh; here's his website.]
