If the list uses ISBNs or similar identifiers, it should be relatively straightforward to create an updated page with links to a source such as OpenLibrary, Worldcat, or Wikimedia's ISBN template (<https://en.wikipedia.org/wiki/Wikipedia:ISBN>).
Though these don't look like ISBNs...
PALS (Library Technology in Minnesota) is now at <https://www.mnpals.org/>, and there might be a URL migration path there.
