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.
