Traditionally, acquisitions related to the Netherlands have included socialism and the labor movement in the 19th and 20th centuries. Since the 1970s, the social movement has expanded to include environmental issues, human rights, squatters, and similar subjects. The legacy of these new social movements can be found at the IISH as well.
In the Russian and Eastern Europe collections at the IISH, Russia and the former USSR are dominant. Additional collection development efforts cover most countries in Eastern Europe that became communist after 1945.
The IISH collections on Germany and German speaking countries in Central Europe cover the period beginning with the democratic revolutionary movements and early workers' organizations around 1840 to the protest movements in the FRG during the '60s and '70s, and the civic movement in the GDR during the '80s.
Elisée Reclus (1830-1905) was far ahead of his time in many fields: he was the first practitioner of the field of social geography, counts as one of the founders of naturism and vegetarianism, led the way at the Paris Commune (1870) and propagated the world language Esperanto.
