If its of any use to anyone, and will certainly save a lot of time manually doing it,
HERE you can download a partial list (only got upto as far as mid G's) of all 3 letter LLL's with archive.org history. Unfortunately its not foolproof, as some of the pages aren't accessible anymore, and the number of pages archived is not really a good measure of how important the previous websites (if any) actually were. I normally put it into 'detail' view and start with the largest files first.
I'm going to continue doing the rest of the list and will post up the rest afterwards. If in the meantime anyone wants the small app. I had written to scrape archive.org then feel free to download it
HERE. Some of you will perhaps remember it from a long time ago, others may not, feel free to make use if it, ask any questions via PM if you need operational instructions.
Cheers
Dave
