I was actually about to suggest something easier: point the readers to
an address that will never change, such as this:

   https://shop.fsf.org/collection/books-docs

Of course, if we can arrange for a more focused URL that won't be
invalidated by bitrot, that would be better.  However, I do suggest to
at least consider the "easy" solution against the risk of a 404 with
the more smart one.
