Electrostatic Machines - Papers

Below are most of the papers that I have found that contain material about electrostatic machines and some other high-voltage generators, and that I have verified.
The papers are in order of inclusion. Most of the fundamental papers, specially about influence machines, are present now. In some cases the text or images (maybe not very good) of the paper are available. Some papers are in the new djvu format, and to view them you need a proper decoder or plugin.

My first sources for these papers were the Rare Book Library of the UFRJ, the Library of the UFRJ Physics Institute, the library of the CBPF, and many references and old papers that I received from friends, specially Lucia De Frenza, from Italy, Hans Bussmann, from Germany, Serge Klein, from France, and Lance Jerale, from the USA.
More recently, many old references appeared on digital libraries in the Internet, some of them listed below and referenced in the list above. The available scans vary in quality, and may have serious problems, specially in Google books, where picture pages of old books, almost always big folded pages at the end of the books, were scanned folded. Other common problems are incorrect names of the works, incorrect dates of periodicals, works that should be in the public domain but are not available for full view, and missing volumes. But anyway, these collections are far more accessible that libraries of real dusty old books.
