Note from JWR:

I occasionally hear from readers that some of the links to third party web sites in my older posts no longer work. Unfortunately, we live in an era where people change URLs and e-mail addresses almost as frequently as they change their socks. If you find any broken links in any of my static pages (the pages available with the buttons at the top of the main SurvivalBlog page) or if you find any broken links in any of the daily posts that are less two weeks old, then please let me know via e-mail, and I will do my best to update them. (I greatly appreciate hearing from you!) But unfortunately, I don’t have the time to continuously update the links in the SurvivalBlog Archives.
