@cclauss LGTM 👍 -- none of these scripts are or have been in any kind of active use for as long as I have been involved. Many will be one off tasks no longer appropriate, and many of the others will no longer function as originally designed give all the changes which have been made.

I don't seem to have access to the new repo. An old PR of mine that should possibly be added for archiving is https://github.com/internetarchive/openlibrary-bots/pull/37/files , which was never merged into the openlibrary-bots repo. The legacy-repo seems a more appropriate location.

Sorry for the oversight. I have invited you to be an admin of that repo. Please add any files that you deem appropriate.

Woohoo! Double-checked olsystem for all occurrences of scripts, and no references these, so I think we're good :)
