For good fun, here are a few of Lenin's most important contributions to Marxist theory, I highly recommend all of them (but Imperialism especially).
Imperialism, the Highest Stage of Capitalism (must read for any Leftist wanting to understand modern Capitalism, Anarchists included!)
Your links don't want to work for me, fyi.
With marx2mao.com, sometimes you have to reload the page to get in. The translations for Lenin's works are bettee than Marxists.org, which is why I prefer marx2mao.com even if the website is worse. You sometimes have to "continue to http site."
For sites like this that don’t have HTTPS, I post archive.org links instead, because nontechnical people simply aren’t going to go to HTTP sites.
Gotcha! Makes sense. I'll start doing that in the future.
