Accurate documentation. It's always been difficult to obtain, the Internet does make research easier in some ways but it also provides more inaccuracies than truth. In many ways the Internet is contributing to the obfuscation of reality. The problem is more and more inaccurate documentation (often based on inaccurate documentation), more artist impressions than actual documentation are showing up and, simply because it gets published, can be used even in competition.
