Have you considered or would you consider to save these gems, debunkings of specific webpages, on Clavius ?

Yes, Clavius started out as a collection of such specific refutations. But in that it tends to get very repetitive I've determined only to specifically address essays that are less ephemeral. Collier's and Milne's articles appear widely and were in print. Web pages are here today, gone tomorrow.

Of course it's probably a good idea to keep something I spent hours on, whether it's ephemeral or not.
