Many separate books in a single digital edition

A digital version that can be offered in a single file and does not fill a CD contains the work of 14 voluminous books + many separate pages + their presentation with a graphical interface. The web pages could have been divided for more than three sites! Storage media have improved and DVD / CD optical discs seem bulky compared to their storage space. Many computers (laptops and desktops) do not have a DVD / CD reader.

The presented books are not all for a separate edition or for sale in bookstores. Their content have formulated by long-term writing efforts that began in the 1980s. More information about the books is available on next pages.
