SPIEGEL archive freely accessible
As announced recently Europes biggest magazine DER SPIEGEL (trans. = "The mirror" - not to confuse with "The Mirror" in UK!) made today articles of SPIEGEL (including sub-magazines and their lexicon) and Manager Magazin at wissen.spiegel.de online available for the public. The material is still copyrighted but it is a huge knowledge dump as the archive contains articles since 1947. The keyword search results not only in a list of articles from SPIEGEL and/or Manager Magazin but also includes entries of the German Wikipedia. There are also dossiers like "Die Sprache des Lebens" (= "the language of life) that combine some articles about selected topics. You can get an overview about the content at the statistics page.
