Google has made it its companies premise to make the worlds knowledge available to everyone. As an effort for that, scanning copyright-free books, papers, pergaments, scrolls, codices,... has happened already and made accessible this or that way. But we see also that a lot of those classical works have been made into nicely edited and commented works by publishers. Some of those works neither contain sophisticated art or elaborate layout. For example if you buy Penguin classics books or Reclam books, their only media is recycling paper and pure text sometimes cursive or fat or underlined with some rare diagrams. But the scientific comments are useful. I have two questions connected with that: If i download a digitalised book fom let us say 1850 of 500 MB size and 240 pages wouldn't it be more efficent to download one nicely typeset and error-corrected and commented version of that book of 1 or 2 MB ? On one side such works are not copyrighted anymore, on the other side publishers greedily guard what should be open to the public because of humanistic reasons. Of course, having a carefully digitalised version of certain works like codices, pergaments aso. available in its original form is of great scientific value, but on the other side it would be equally important to have derivative works available in the public domain. It is also known that most modern textbooks which cost in shop hundreds of bucks can be downloaded these days form more or less obscure sources for free. So the facts are that the scientific community is a bunch of money-mongering greed-puppets and the ideal of free science gets only fulfilled in obscure channels. In effect this displays modern scientists with a career as unworthy of their jobs whereas those people who want to relate to the free scientific community are criminals so to speak.
