The archives for this list do not appear to be searchable, and there are some large (4-year) gaps. Is there a good (easy) way to search the archives? Or do I need to download them all?

Actually, I would settle for a way to just download the entire archive without having to spend an hour or so rowing at the keyboard.

Fortunately, I have archived the last year or so on my own computer, so I have been able to find information that does not exist anywhere else on the internet (AFAICT).
