As a part of Wikiconference North America, which was a pre-conference to Wikimania 2017 in Montreal, there was a Scan-a-thon at Bibliothèque et Archives nationales du Québec.  Wikimedians and new volunteers worked with staff at BAnQ to scan documents, upload high resolution TIFF files to Wikimedia Commons, and add metadata. Tours were also given by BAnQ to see their "New France" archives, which contain genealogical records not just for French Canadians, but for territories before the Louisiana Purchase was made in 1803.

Wikimedia DC had an editathon at Heurich House Museum, which is a private museum often called the Brewmaster's Castle. The event was one of the signature events of D.C. Beer Week, and saw more than a dozen participants, including scholars, historians and museum studies majors in the DC area.
