The Internet Archive describes itself as a library but it's so much more than that. The site boasts massive collections of vintage media from stock photos and footage to audio recordings and books. For anyone interested in the history of computing though, it's a dream come true. Offering more than just descriptions and details on classic software, the site lets you run the software through in-browser emulation. And while it already houses scores of classics, it's continually adding more. It has now added classic Macintosh computer software in a new collection.
