The Airplane Propeller

Books are still among the most important cultural achievements of humanity. Their invention was as important as the Internet: for the first time, a mass transfer of information became possible. Education, science, research, but also entertainment was based on a new revolutionary basis. Books are changing society until today.
The technical possibilities of mass printing led to a radical increase in titles in the 18th and 19th centuries. Nevertheless, the conditions were still very different than today: Who wrote a book at that time, often wrote a life's work. This is reflected in the high quality of old books.
Unfortunately, books age. Paper is not made for eternity. Therefore, we have made it our mission to preserve the book of knowledge of humanity and to make old books available in high quality at low prices
