The Juristisches Internetprojekt Saarbrücken (the best portal to start looking for German law, and it contains international links too) always has a link of the week. This week the link is porticolegal, described in German here (with past links of the week below).

Porticolegal offers news, statutes, case reports, literature, a search for lawyers, links to professional associations and universities, online journals and discussions forums, and much more.
