The Beijing Municipal Archive (Beijing shi dang’an guan 北京市档案馆) stores, as the name suggests, materials pertaining to Beijing as a city. It has materials on both the period before 1949 and after. Arunabh Ghosh has already written a very informative review of this archive on Dissertation Review, based on his experiences in 2011: http://dissertationreviews.org/archives/643. Therefore I will only give updated information on the aspects that I found changed, when I visited the archive in February and March 2018.
