Atlas Shrugged is a primary source? I'd recommend leaving that novel until later. If you want to read up on Ayn Rand's ideas, I'd suggest some of her non-fiction collections, like Capitalism: The Unknown Ideal which also has some essays by other authors.

But let's be clear: Pretty much everything on the subject is going to come with a point of view, and often isn't going to have much to do with the real world. For instance, what Marx wrote about, and what actually came about in the real world, are two very different things.
