Internet Archive
Damn, I found a great website.
So this, internet archive is a website that is built by the nonprofit organization. It archives so many things: video, software, books, audio, etc.. We can access many old files here, even the books that released before 1928.
What even more mindblowing is the its project named Wayback Machine. It crawls things in the internet and archive it. Because of this, please be aware of everything that you post in the internet WKKW, because once it's publicly posted, it's captured and archived💀
