Could you build a well-designed and easy to use interface which taps into the wealth of information and knowledge available on Archive.org? Would it be kosher according to their terms of use? I can imagine this would be a great project or who knows, a startup even.

When I visit that page I see almost nothing but file download links.

Yeah, 100s of little files doesn't increase the reach of information, to lessens it. My beef isn't with the information but the presentation. Only the most diehard autodidacts will push through these barriers.

Left column, all the way at the bottom, "All Files: (HTTPS)"

No this only switches the connection to https, but still hundreds of files.
