Collective Library

Our goal is to preserve Amsterdam's knowledge and make it available for everyone. Now you have the chance to list your own collection and turn the city into one big library.

But wait...
why would you
even share?

Good question.
That's truly up to you but what do you think about that?

Get connected with
like-minded people

Sometimes it's hard to find people with the same interests. Connect with like-minded people.

Contribute to
knowledge preservation

By sharing your knowledge through OBA, you make it also available for the next generations.

Keep the collection – share the information

You keep the items in your possession. We just enable you to list it in OBA's online library.
