I mean, even a text book was a nightmare for me to look up on Amazon, because they let you self publish anything too... So I appreciate anybody trying to build something like this up.

Curious, since I didn't look are you hoping to (or are you already) earn some side income to fund this going forward via affiliate links?

I say this knowing full well, maybe some of the results wont get you any income, but the ones that do might be worth keeping in results. Side projects eventually burn a hole in your wallet.
