That’s the direct translation of “Biblioteca de bosillo,” the title of this piece on Not Made In China. Everyone on this planet has either been in a tiny apartment or had to move a poop-load (metric, not english) of books to a new apartment. This takes care of both problems. Maximize space with ultimate portability. And if that’s not enough incentive to buy, here’s another: street vending. Load this puppy up with all your old, crappy books… roll it down to the [insert highly-trafficked local thoroughfare], and away you go. 50¢ each, 3 for a dollar.
