Project Gutenberg Europe currently doesn't make audio EBooks. Project Gutenberg (US) makes audio eBooks available for some of the same great literature available in plain text. Thanks to Mike Eschman for most computer-generated eBooks, to AudioBooksForFree.com for our Arthur Conan Doyle series of human readings, and to LiteralSystems.org for work on new readings by volunteers.
Our listings are divided into two categories. We are actively adding new audio eBooks read by people, primarily through work by LiteralSystems.org. However, we have stopped adding computer-generated eBooks. Instead, we are working on methods to automatically make computer-generated eBooks on demand (that is, by choosing options, then getting the file within a short time).
