Here I have composed a list of 25 books that I think are readable and among some of the best nonfiction books of all time. This is, of course, not a definitive list, and I am sure to have missed some of your favourites — to compose a definitive list of the best nonfiction books of all time, one would actually have to know everything about everything. These are books that are well written, have had an impact on our understanding of the world, or are books that deal with important, profound themes. I have excluded memoirs, autobiographies, and poetry, for I felt that the scope of this list is too small to do justice to such a wide range of offerings.
