> How often do you 'vet' authors of non-fiction books prior to reading the book? I misread the question as 'How' rather than 'How often', but I'll repeat Jerry Weinberg's heuristic. He'd wait until three people he trusted recommended a book before reading it, as a way to filter for quality. He used it as a way to manage his limited time ("24 hours, maybe 60 good years" - Jimmy Buffett), but it also works to weed out books not worth mentioning. In terms of 'how often', pretty often.
