There are a multitude of genres in the nonfiction category. Many of them overlap, and some of them cover very niche subject matters. The main nonfiction genres are: narrative nonfiction, historical nonfiction, biography/autobiography, memoir, travel writing, philosophy, religion and spirituality, self-help, science, medical, psychology, art, crafts, DIY, photography, gardening, food/drink/cooking, computers and software, health and fitness, political science, business and economics, parenting and family, education, and music. Plus, within these areas, there are books which are even more specific and specialised.
