An old profesor of mine who used to review computer science books as a side gig told me he never bothered to read them, all he needed to do was check the contents page to see if they were good or not.
I've been applying that method for figuring out whether a non fiction book is good or not and it works like a charm.if the contents are in a weird order or there isn't the right amount of specificity in the contents its prob not good.
Also don't commit to reading any big non fiction books without checking Wikipedia and doing some 30 min research on the topic first. Easier to spot the bs that way
