I don't agree. Giving 30 books vastly increases the chance that any given reader can find the "right" 20%. Your 20% might not be mine; although I would find it interesting if you posted your top 5 books, I'd rather see the 30 that you read, so that I can read them all and find my own top 5.
My reaction tends to be opposite yours: when someone gives me the "top 5", I consider it only a trailhead; it's unlikely my top 5 would be the same.

That's a fair point. The important part, it seems, is identifying not just which books to read but why. That information would help you and I find our 20%.
