[Franek Grabowski]

Oh, you do have authors at Wikipedia, although hidden by nicks, sources are also listed, as well as you can browse history of changes. You cannot see that in printed encyclopedia. The problem is with their QC, some chaos in the articles, no cross check between various language versions, and sometimes, a political bias.

I can assure you I have seen so much pure BS & crap in respected printed books, that I certainly do not consider paper and ink a proof of anything, but a possible use for fish & chips due to lack of printed newspapers.
