I have about seven bookcases. It is a bit crowded in the living room and the bedroom with bookcases but am horrible at giving books away. It hurts. In the living room i even have one behind a door. You dont see the bookcase when the door is open but it was what someone called wasted space. Perfect space for a bookcase. Several pof the pockets also stand in two rows, one behind the other. King among them. But sometimes books just disappear in a creepy way. It has been years since a saw my copy of Dead zone. It like it evolved legs and run away. But mostly they stay where i put them. I've managed to keep books from the kitchen and the bathroom but otherwise..... The two soragerooms that go with the apartment is also full of books.
