Traditionally, the answer would be "Use PURLs". The Internet Archive happens to operate the purl.org resolver.
Unfortunately, with the recent attack, the purl.org resolver went offline and remains so. All the purl data is still there and is accessible to the public, you just don't get resolvable URLs for them.
Nowadays, it seems like ARKs are the better way to go, anyway, and the attack on archive.org proved it perfectly. Look into <https://arks.org/>
(The Internet Archive mints ARKs for every item uploaded to its collections. You may have noticed them in the infobox below the fold when looking at a given item.)
As for your latter remarks, the Internet Archive will take just about anything. Create an account and start uploading. Ted Nelson has a huge chunk of his papers on there.
