You can store your books on the ceiling and access them by pulling pulley cords. This way you can store your books on the ceiling and save space in your apartment.

The books are stored in many individual "cases", or containers for books. Each case holds about 10-15 books. Your ceiling bookcase is made up of many of these cases fit in a grid.

Viewing Options.

1. Each case has an index that lists the books in that case. This would probably be too small to read properly from the floor.


2. Also possible are words for things that "hang over your head". Like "DEBT" and "ANXIETY". Just to externally represent "things that hang over your head" on a system that physically hangs over your head.
   
3. When you look up you see the bottom of each case with a photograph attached, so you have a mural composed of different images, such as clouds or the sea. Most calming would be photographs creating an image of an ambient space, or one of gently sleeping animals in a soft wood.

But wouldn't it be better if the book-cases were tilted so you could see the spines of the books themselves? There could be some cases that are upside-down or otherwise "hide" their books: this way you would not have all of your private books, such as "The Joy Of Sex", dangling over your guests.

Attachment Options:

The question is, how would you stop the books from falling out if they were spine-down? Thats difficult.

1. Each book could be squeezed between adjustable metal plates that are tight enough to stop it from falling out.


2. Less practical would be painting the page-edges of each book with magnetic paint and then making the case magnetic. You still want to be able to read the book.


3. Another options is that the cases have clear glass or plastic bottoms, so the books fit in slots but are held in because the cases are closed.

Retrieval Options:

1. When you want a book, you pull on a pulley and the case lowers to the floor. However, if every case had a pulley rope, you wouldn't be able to walk in the room because it would be full of ropes, like a forest of trees.


2. Each case is attached via a retractable cable and there is a control panel. You type in the number of the case you want -- "A1" for instance -- and that case is lowered to head-height. When you're done, you can either hit the control panel button again (or a button on the case itself) that will cause its pulley to retract.

Arrangements would have to be made for cases to fit different sized books: your mass markets, trade paperbacks, coffee-table books (though perhaps you wouldn't want those on the ceiling but on the coffee table), textbooks, etc.
