Ask HN: Is there a repository of failed startups (re-usable startups idea)?

I was wandering if someone keeps records of failed tech/internet startups and their codebase?

Maybe it's not a bad idea to go back and re-use some of the failed startups whether it's a codebase or just a business model. I found a lot of reason for failed startups but not many use cases - mostly scattered around the Internet.

If someone would built such a database would you contribute your failed business model and codebase?
