The open bookcases of Offener Bücherschrank can be found at three spots in Vienna (see the website for other locations!). The concept: go there, have a look, take what you think you need to read and enjoy / bring it back / take more back than you got in the first place.
Why do I like this? Because books weren’t made to stand on the same shelf for their whole “lifetime”. The way I see it, share what you think is great! And even if you do not like or understand a book, maybe someone else will – so why not give it away?!
Since the contents change permanently, it cannot be said how many books one might find in English, Turkish, Chinese, Arabic or Esperanto. In case you are looking for a specific book, better try the main public library.
Everyone else: experience the unknown ~ happy reading!
