Deletion of Otomar Hájek

Comment: May I suggest that some of the 'keeps' here actually ''find'' and add some of these sources to the article? I looked and couldn't find any significant coverage of him at indepedent reliable sources, but if some of you who say they are out there can find some, I'd be quite happy for this to be kept! Saying that they are there and not adding them to the article seems to me to indicate that you haven't actually found the reliable sources which would demonstrate that he meets  - I couldn't find evidence that ''The person's research has made significant impact in their scholarly discipline, broadly construed, as demonstrated by independent reliable sources'' (#1), which I presume is what the 'keeps' are suggesting? I also can't see how he meets the other criteria for inclusion, hence why I brought the article to AfD
