@ajroach42 @Neonriser Exactly.
I started to write my own crawlers circa 1995 but I saved only a few major sites en toto over the years. I settled mostly for using Scrapbook X to save pages of interest.
I've started to build a curated collection now using next-generation tools. I hope to snail-mail 100s of copies out before I pass away. Offline devices can't be taken down. Link me to copies of science-paper archives, leaked data, and/or your own creative works to go into the River of Time.
