"Wikipedians in residence (WIR) have been around since at least 2010, with the first one hired by the British Museum in the U.K. Since then, other museums as well as universities, archives, libraries, art galleries and health organizations, have followed suit with a total of 165 WIRs hired worldwide. According to the Wikimedia Foundation [...], right now 65 WIRs are actively working — and registered — with the foundation."
