Floorsies or Boxies might be more accurrate.
Just 2 of some 9 boxes of smaller books stored under my bed. We lived in small spaces for some 20 years. While i didn't mind storing fiction in sheds, save for a few classics/favorites i was not putting my various gift, uplifting and meditationals out in the cold. Periodically i switch out the shelf i have in the living room of such books. Despite having almost doubled our square footage with this home, we still don't have everything 'out'. Eventually hope to have floor to ceiling (they're 8 ft high) walls of shelves so we can.
