I was reading up on strings articulations (8Dio Adagio Violins has a "Loure" articulation which I wanted to read up on)
Wikipedia has a page Violin talking about playing techniques.
http://en.wikipedia.org/wiki/Violin_technique
In one of the links there is a link to The Violin Site, that has a page that has detailed instructions on how to execute quite a few articulations.

Finally I went to YouTube and found some instruction videos for Violin playing techniques, where the very patient Fiddlerman shows how he achieves various playing techniques on the violin.
Its great reference to see people showing how they play various articulations.
