A key aim of this guide is to point you to the incredible amount of material you have access to for minimal or no additional cost (e.g., via Internet Archive, Amazon’s “Look inside” feature).
Where I’ve included links to Amazon, I’ve also included corresponding links to the same resources elsewhere (e.g., Google Books) wherever I’m aware of them. That said, I want to be clear that, where this guide includes links to Amazon, these links are “affiliate links.”
This fact means that, if you click one of these links and make a purchase, I’ll receive a modest commission from Amazon at no additional cost to you (additional affiliate disclosure information). These links are simply a way of having Amazon defray some of the costs of making this material available to you.
