I am going to write an essay about Hayek's views on economic and political (individual) liberty. I am trying to find books to develop a positive discussion on the topic, but I do not know where to search. I started with J.S. Mill's "on Liberty" and Hobbes' "Leviathan", but I cannot find where Locke discuss subjects such as individualism. Also, I was thinking about reading anarchist idea on the topic as an opposing view. Is there any good reading I've missed so far?
Hayek's The Constitution of Liberty is in my opinion the place to start. It has a lot of references to John Stuart Mill (which whom he strongly disagrees, btw), and puts forward his argument on freedom. There is also a very recent (but rather long) analysis of Hayek's book (available online here), which dissects his influences.
