I too have a barrister's bookcase and have been contemplating emptying it for quilt storage.
Out of Christmas, my Christmas quilt is stored inside a pillow sham sort of a cover that coordinates with the quilt. Just that it has nothing Christmas-y on it! So I can leave it out for decoration.
Smaller wall hangings are hung on coat hangers in a suit bag.
The spare bed has been known to have many quilts on top!
