PS : I wrote previous posts assuming the internet/google was still what it was. Checking now, it seems like archaeology is an entire topic that's been scrubbed. Searching paleoindian + pdf used to bring up 10 or so pages of site reports you could read for free. No more. Everything left, nearly, is behind a paywall.
Now, searching for "French artifact + limace" in images links to nothing. Even specifying sites like Dons Maps : zero.
The dumbing down continues. Highschool kids can no longer place the American Revolution and the War Between the States in the right centuries. (!)
I tried duckduckgo, dogpile and yandex just now, and they seem to do OK. It's google (and bing, that piggy backs on it) that stink.
