I posted about bookish festivals before. Make sure you enter your local bookish festivals here! I found one that is worth a separate mention. Every year on April 1. the “Edible book festival” takes place in a lot of countries. “This festival is a celebration of the ingestion of culture and a way to concretely share a book; it is also a deeper reflexion on our attachment to food and our cultural differences”, the organisation writes on their website. You can find it here.
I have put a short cut to bookish festivals in the side bar. I would love it to grow out into a some sort of world wide database of festivals concerning books and reading. So if you have the time, please enter festivals concerning books in the comments of the article.
