Slightly off topic, but I find the increasing use of WIKIPEDIA as a historical source to be a disturbing trend. When you know a subject because you have researched it in reputable books and you then compare with Wikipedia, it is amazing to see the distortions and outright lies that get posted.
The worst example for me is the so called "Chenogne massacre" which has its own entry and is often listed as an example of a massacre of german POWs by allied troops. I have been reading about WW2 for 40+ years and had never heard of this until it started popping up on the internet a few years ago. I grew suspicious when I first read it and some months ago I took the time to track down all the sources listed in wikipedia and to do my own research.
As far as I can tell, it never happened and is a totally made up internet event. There is no eyewitness testimony or any other proof that the massacre ever occurred, yet it has its own wikipedia entry:

All the "sources" listed lead to other authors who quote other authors, none of which list any references to back up their claims.
