Rub-a-Dub Style: The Roots of Modern Dancehall is Beth Lesser’s in-depth and academic book documenting the Jamaican genre from its inception to its current form. The excellent 350-page title is now available as a free download from the Beth Lesser site. I got in touch with Beth and she said this was in order to reach a wider audience and also to retain creative control over the endeavor. The printed version is also available at Lulu.
