THanks!
Just making sure I hadn't missed something in the Preferences. It's not mission-critical, since it's not like I have too look in too many places - just two (unless I get a MemoryStick!).
It's a great idea to assign collections/tags to locations. With books coming on and off the device from the public library, I think it would be too arduous for me to try and manage the collections by location. I'm too cheap - I'll sacrifice a few seconds for searching in favor of free books
