The European Commission will propose drafting rules that would make it easier to put many books and manuscripts online. The move is a part of the commission’s effort to bolster access to information and to encourage online businesses. The changes would be aimed at allowing Internet users to access out-of-print works and so-called orphan works for which it is impossible or very difficult to trace the rights holders, said Viviane Reding, the European Union commissioner who oversees the Internet.
