Well,  if you are thinking about there are many books which are classifieds in many other types such as Action story books, Horror story books, Adventurous books, Mystery, fantasy, Historical, Scientific and etc these are just the types however you should fall in love with the Genres of books

What are Genres - nothing but the style or a category, specialty of authors which they are artist of describing or relating to a style of writing  depicting scenes from ordinary life, typically high visual situations associated particularly with mid historical and present containing situations

After-all books are categorized in only two types in common if we think

  1. The narrative books includes story of someone's life which teach the readers and writers to watch their life-story the way they had looked at it with full of suspense and climax.

      2. Knowledge based factual books in which each and every sentence have life which is compulsory and made up of truth and experience.

Commonly those are known as Fiction(story based) & Non-Fiction(Knowledge based)

Fiction: She: A History of Adventure, Corporate Chanakya, The Dale Carnegie Anthology etc

Non- Fiction: The Lion, the Witch and the Wardrobe, Think like a Monk etc

Some of the above are Fiction and Non fiction book types - and might be my upcoming index of summary:)
