Many (many!) years ago, I survived a class on Milton's Paradise Lost by signing out an annotated version

Why am I talking about English literature in a blog about business & economics resources? Because it's a great example of how we all sometimes need a little help with complex topics. In many cases it's far simpler to bootstrap your learning by reading a book about a theory before you tackle the theory itself. (Even, to be frank, as a substitute for tackling some particularly difficult theories!)
Fortunately, there are shortcuts! Sometimes you can avoid falling asleep on piles of convoluted texts and instead get a good sense of a topic in the time it takes to ride a bus to school.
