Its authors, representatives of the world of science from Poland and other European countries, offered their reflections on the future of festivals, indicated the challenges currently faced by the organisers of science events, pointed out the necessary changes, as well as proposed new non-standard solutions that will help science reach an increasing number of recipients in the most accessible way. The impact of the pandemic on the organisation of Polish festivals was discussed by Dr Anna Budzanowska (Undersecretary of State in the Ministry of Science and Higher Education), Prof. Ryszard Koziołek (General Director of ŚFN, Rector of the University of Silesia), as well as Wiktor Niedzicki, Jarosław Juszkiewicz, Dr Arkadiusz Gorzawski and Dr Mikołaj Marcela. The European science communication initiatives were represented by Dr Annette Klinkert (Executive Director of European Science Engagement Association), Amanda Tyndall (Festival and Creative Director of Edinburgh Science Festival) and Jennie Turner (Operations Manager at the International Science Festival in Göteborg). The publication also contains a report on the 1st Forum of Polish Science Festival Organisers.
