The International Institute of Social History has digitized several more of their important collections, as part of a large-scale digitization project. The collections include Max Nettlau's papers, the Bakunin collection, the Louise Michel collection, the Alexander Berkman papers, the Fédération Jurassienne Archives, the Lucien Descaves papers, the Gustave Landauer papers, and several others. Many of the downloadable files are manuscript pages, varying dramatically in legibility, but there are also files of collected pamphlets, periodical issues, fliers, etc. So far, I've run across some issues of Josiah Warren's Periodical Letter, a good scan of J. Wm. Lloyd's "Anarchists' March," the published first section of Louise Michel's Notions encyclopédiques, par ordre attractif, clippings of early poems by Joseph Déjacque, etc. The Nettlau and Descaves collections are particularly rich in longhand copies of published articles, including some early pieces by Ernest Coeurderoy and Déjacque. Together with the Proudhon-related manuscripts still appearing at the Ville de Besançon site, there are whole worlds of radical history opening out there right now.
