Are there any copyright regulations to be careful about?

The EOD network is mainly dealing with public domain books, published between 1500 and 1900. Nevertheless, some partner libraries also allow digitisation of books beyond that timeframe, namely for special user groups, e.g. researchers or for people who are visually impaired or blind. Again each library is free to decide which books are made available. Basically, each library has to base its decisions upon their own local and national policy and regulations.
