A fact used to be a way the world is. That's why your English teacher was eager to correct you when you used the phrase "true facts." All facts are by their nature true. Or, even more pedantically, a fact is real, and only your statements about facts can be true or false. This has come to matter more as data has become more central in the ecology of knowledge. Factual.com is pretty clearly about facts. Its databases generally contain the sort of information that you'd definitely want to correct if it's wrong. For example, its table of 6,661 beers of the world lists the brewers, the style of beer, the country and region, and the sorts of information included on a nutrition label.
