We are avid readers of Hacker News and often come across high-quality discussions from the community. We also figured that the books people discuss must be quite good, and so we built Hacker News Books, which aggregates the top books found in comments and ranks them on a weekly basis. To keep visitors up-to-date, we also offer an email newsletter. The website is sustained via referrals from Amazon book links.
Hacker News Books is an independent project, unaffiliated with Y Combinator.
All links to Amazon, Safaribooks and O'Reilly get extracted once a week from Hacker News posts. We then rank the links based on how often they are mentioned and the karma of the user on Hacker News. So books mentioned several times by different people having high karma tend to rise to the top.
