I have a tall bookshelf in the reading/quiet corner. "Oldest" books are higher up, and so on, with board books at the bottom. Some vintage books (as in, books I had as a baby, LoL) on the very top shelf.
However, I have been thinking about putting a shelf up at the calendar corner, for our "theme" books. Currently, I just keep those in a basket by my chair.
Something like this?
