I came across Theologie-Skripten the other day, and thought I’d pass it along.  It focuses on theology, but as the author addresses various issues, he gives a nice overview of ancient sources–biblical and non-biblical.  So if you are looking for 2-3 page translation excercises that relate to different topics or are just want a quick idea of texts that relate to a subject, this might be a helpful place to peruse.  Also, it’s got a decent amount of German bibliographical lists about different topics.
