Biologist Lars-Gunnar Bråvander sells out his library of over 100 nature books. From 17:00 the books will be available for a first look. Show your interest in a particular book by putting a post-it note with your name on it on the book. Books with only one stakeholder will sell for 20 kr, books with more than one stakeholder will be put out for the auction which starts around 18:00. Bidders under 30 pay half price, even on books won during the auction.

Come find a new favourite book, meet like-minded people and support the local non-profit organizations Uppsalas Fältbiologer and Upplands Botaniska Förening who will share the surplus from the auction. Bring your own bag, payment via cash or Swish.
