Ask HN: People are interested, now what?

What makes you not see that potential here? Seems like the obvious answer, at least if this is aimed at being a nice small profitable side project.

The traffic was from the one time hn submission. Now you have to find other traffic sources then use affiliates non-amazon since they closed your account.

add a buy me a coffee or patreon link? some users will support a valuable adfree resource especially if you explain hosting costs

It seems like before you think about monetization, you should think about how you can generate the amount of traffic you had in February repeatably. February had 6k visitors, but March had 350, and August had only 240. It's going to be pretty hard to generate any revenue from a website that links to free books with only 8 visitors per day.
