Karl Marx & Friedrich Engels Papers Digitized and Now Available Online

From the International Institute of Social History:

The original papers of Karl Marx and Friedrich Engels, World Classics, are digitized and now online accessible. The papers can be consulted from anywhere and by anyone who logs into the catalogue website of the International Institute of Social History.  Access is open and free.

These famous and precious archives are used intensively by highly specialized researchers. They are among the most influential pieces of writing in world history and still play a major role in the rethinking of capitalism, labour, economic crises and revolution.

Non-academics will enjoy the historical sensation of having these papers at their fingertips – reading them would be another matter, as Marx’ handwriting is extremely fiddly.

In June 2013, the only surviving handwritten page of the Communist Manifesto (1848) and the first edition of volume I of Das Kapital (1867) were inscribed on the prestigious UNESCO Memory of the World Register.

The Marx/Engels papers have been preserved at the International Institute of Social History (IISH) in Amsterdam since 1938. The digitization of the archives was a most complex job. High-quality digital master files will be kept in a digital repository. Derivatives are accessible through the IISH catalogue website, the Europeana Digital Library  Europeana and other platforms.

How to Access

The International Institute of Social History is an Institute of the Royal Netherlands Academy of Arts and Sciences (KNAW)
