Abstract
The problems that the great developments in digital information and the Internet are creating for copyright may be partly solved through new legislation as well as through the implementation of technological systems (generically known as ECMS) that help protect it. These two approaches – legal and technological – interact, as the new copyright laws protect these electronic measures through the prohibition of their circumvention. The contents of the three main legal norms that have regulated this area to date, the US Digital Millennium Copyright Act, the European Directive and the new Australian Copyright Act, are analysed in an attempt to determine what impact they might have on the traditional limitations and exceptions to copyright (fair use/dealing, private copying, library privileges) that benefit libraries, their users and the general public.
