It’s been a tradition at these kinda gathering that we call out to everybody to bring at least 1 book of common or purely personal interest.
With such a great group of diverse participants this will lead to a super interesting collection of readings to have a temporary library setup during the retreat in Klöntal. There is something unique about a “physical” reading place with the people who brought the books present at the same time.
but of course… also you can put it on the wiki. such as this great collection of readings put together during HackteriaLab in Yogyakarta.
