In this joint workshop Tim de Haan (Nationaal Archief) and Olaf Janssen (Koninkijke Bibliotheek) will give an overview of why and how the KB and NA have set up structural collaborations with Wikipedia and its sister projects. Starting from a brief historic overview of their joint Wikipedian-in-Residence project in 2013-14, Olaf and Tim will discuss the added value and best-practices of the currect Wiki-activities both institutions are running along with the Wikipedia-community. They will talk about the rationale and impact of image donations, a project to systematically describe all Dutch WW2 resistance newspapers on Wikipedia, the collaboration with public libraries, volunteer engagement activities and how staff members experience the sometimes abrasive yet polishing nature of working together with the Wiki-community. And of course Tim and Olaf will share their personal observations of being part of the global Wiki-family.
