Press release IISH-KNAW

Marx & Engels papers completely available online

11 August 2015

As from today, the papers of Karl Marx and Friedrich Engels can be viewed free of charge and in their entirety through the IISH’s catalogue website.

Historical sensation

The writings of Marx and Engels are among the most influential in world history. In the twentieth century much of the world was ruled by regimes claiming to be Marxist, and the writings of Marx and Engels continue to play an important role in thinking on capitalism, labour, economic crises and revolutions. The Manifest der kommunistischen Partei has been translated into almost every language.

Many people would regard it as a historical sensation to be able to see the original documents, though you have to be particularly determined if you really want to read them: Marx’s handwriting in particular is virtually illegible.
The digitized documents can be browsed and each item viewed in full-screen mode.

All the documents can be downloaded as a PDF file and printed. Go to for more information.

About the International Institute of Social History (IISH)

Work and labour relations deeply influence how we live. The International Institute of Social History (IISH) examines how these relations develop globally over time. To conduct this historical research and support other researchers, we collect archives and data from all over the world. Established in 1935, the IISH is one of the world's leading research institutes on social history.
Since 1979 the IISH has been an institute of the Royal Netherlands Academy of Arts and Sciences (KNAW). The collections, some of which concern politically sensitive materials, are the property of or have been issued on standing loan to the independent IISH Foundation.
