The HDMA sounds so formal, like some kind of ancient tweed-wearing, tea-sipping committee. And, while they are building a library, it's far from dusty and silent. It's a collection of surprisingly lively and diverse maps-- all unique, all hand-drawn. And when you think about it, if necessity is the mother of invention, doodling could very well have begun with directions to the laundrymat.
