Some replication of some downloads from elsewhere, but also some information I haven’t seen anywhere else:

Surf around the parent directory, but between the JPG collection and the survival books, I found these two links to be the most useful portions of the site:

Spreadsheets for every imaginable thing. You might want to poke around the parent directory as well. Obviously there is a focus here on agriculture, but see if anything else interests you:

Most of this sites stuff is repetitive, but since many of these sites seem to drop off the net without warning, it doesn't hurt to have a backup site with similar material on it:
