Mark, aka The Sanderson Collector, has collected over 1,000 Sanderson books, runs a popular informational YouTube channel and Instagram feed on Sanderson collecting, is a beta reader for Sanderson, and is a founding member of the Sanderson Collectors Guild.

In this book, he collects his knowledge for the first time, explaining how to understand the jargon of collecting, how to identify collectible books, where to buy and sell these books, and how to care for your collection.

This is followed by a comprehensive list of over 250 of the most collectible Sanderson editions, including all ARCs, 1/1 hardcovers in the US and the UK, leatherbounds, and many other rarities. Each entry has details about the book, and an estimated value based on recently observed sales. Also included is a guide by Murphy Thomas for the most collectible Sanderson swag.

Mark will play Axies the Collector in the Stormlight TV show, according to Brandon.
