:: Sorry, but I'm not convinced by your arguments. What you imply is that we editors can question a reliable source arbitrarily- when we agree with it, we use the info, when we don't, we delete it. If a leading Romanian literary weekly, Romania literara, a reliable source as you yourself has agreed, says that his book got the award, we can use that info, I suppose. Whether you or I have ever heard or not of the "American Society for the History of Culture" or of the National Book Fair (which is a translation of "Tîrgul Național al Cărții" as it is in Romanian in the source) is irrelevant. There was actually a National Book Fair in Los Angeles, the first one taking place in 1936, but if it is the same one or not is again completely irrelevant to this discussion. Just because things cannot be found with a search engine does not mean that they are false, but again, this is also irrelevant. If, let's say, the New York Review of Books said that a certain American book had won a prize in 1974 at a book fair in Romania, would you delete that information too, because Americans don't know much about Romania, and you can't find anything about it on the net? 

 ::I repeat from WP:VNT, "editors are not making judgments as to what is true and what is false, but what can be verified in a reliable source" because your idea of common sense might not match mine. So, it all boils down to whether "Romania literara" is a reliable source or not, I guess.
