Yes, it can be tricky. But this is true of all information sources to some degree, and the problem is usually solvable with simple heuristics and some search effort.
Asking people who you trust for recommendation might be a better heuristic than seeking a book yourself. In this case I think asking other LessWrongers is a good strategy.
