# Books

There is a large number of books on service design out there. We highlighted some of our favourites in this article on the [top 20 design thinking books](https://www.smaply.com/blog/top-design-thinking-books).

Furthermore, we strongly encourage you to read the business bestsellers This is Service Design Thinking and [This is Service Design Doing](https://www.thisisservicedesigndoing.com/). TiSDT is the theoretical foundation and the background why Smaply was founded, and TiSDD comes with an extra smaller book on how to go about Service Design projects.
