According to Guinness World Records as of 1995, the Bible is the best-selling book of all time with an estimated 5 billion copies sold and distributed.[1] The Quotations from Chairman Mao Tse-tung, also known as the Little Red Book, has produced a wide array of sales and distribution figures — with estimates ranging from 800 million[1] to over 6.5 billion printed volumes,[2] with some claiming the distribution ran into the "billions"[3] and some citing "over a billion" official volumes between 1966 and 1969 alone as well as "untold numbers of unofficial local reprints and unofficial translations."[4][5] Exact print figures for these and other books may also be missing or unreliable since these kinds of book may be produced by many different and unrelated publishers, in some cases over many centuries.
