Gary, thanks for this! I think this will be helpful as we periodically get issues submitted asking about dead links -- will be helpful to have it more visible on the license list page.

Hi Matija, I think that if there is a desire for an Internet Archive link, that's probably most easily handled by a PR to the particular license XML file in https://github.com/spdx/license-list-XML to add to (not replace) the cross-references. I don't expect that the publisher tool will automatically add them in, or that the license list maintainers will hunt for replacement links across all licenses -- but if the community submits PRs to supplement with links for particular licenses, I think those would be merged.

Best,

Steve
