8. A Message to Garcia – 40 Million
By Elbert Hubbard
Clocking in at around 1,500 words, this short essay was published in 1899 and is based on the real hero of the war in Cuba. The theme of labor brought out here remains to be relevant up to date as it addresses the relations of workers and their employers. This theme is so appealing to employers and as such more companies had to buy these books and distribute them to their employees. Selling around 40 million copies is a huge dealt that this book is considered one of the best selling books of all time.
