Archives are rarely dull; all that is needed is enough perception to see the drama of the whole human condition, the romance even, lying hidden in the documents. And nowadays, with many IISH archives digitized and accessible online, any interested observer can experience this from the comfort of their favourite armchair.
For instance, anyone can find the picture postcard written on 25 March 1939 by the Italian anarchist Ernesto Bonomini, who was interned in the Rieucros concentration camp in Lozère (France) :
"A scene from the life of the convicts in the first labour camp of the Grand Democracy France, created by his excellency Sarraut to extinguish the Love of Freedom fostered by the exiles...May the revolutionaries of this land keep this in mind. "
Ernesto Bonomini (1903-1986) went to fight in the Spanish Civil War and worked for the anarcho-syndicalist federation FAI. After Franco's victory, he was interned with some 200 other Italian comrades in France. The labour camp at Rieucros was created by the minister of the Interior Albert Sarraut. The document, along with other letters concerning this horrible episode in the history of France, can be found in the archive of Luigi Bertoni (inventory no 107). In April 1939, Bonomini managed to escape from the camp. In the end he worked as a paperhanger in Hollywood, USA.
