More than 7,000 works by over 1400 authors - That sounds great times. And it would be if we had thought before going to work. The 7000 works are as .xml files. The Google Chrome can except (we learn only when you buy and open the DVD has) reflect any browser. To play it even with Google Chrome, you have to read the DVD and all .xml rename in .html. And not just at the 7000 levels, but with an HTML editor in all references and tables of contents, of which there are countless. As easily occur 1-2 weeks working together. BUT: If you can then play the DVD content on the PC, you have no page numbers or other indications, with which you can highlight text passages! And you read even a book 100seitiges and find every time the place again where you left off! Since eBook readers only come into question. And for the DVD is not intended. The authors recommend the DVD on request, to convert each of the works with Calibre into an epub. One has then but already ask what you then outputs 31/40 if you must invest to work a hundred times more, to be able to read the works of the eBook reader. And that's where it is all digitized books from Project Gutenberg same as EPUB. Too bad that you have made so much work and the only sensible target group, the eBook reader, outside before leaving. Since the Spiegel-Verlag has taken next.
