Books remain one of humanity's most important cultural achievements to this day. Their invention, alongside the introduction of the printing press, was as significant as the internet: for the first time, mass dissemination of information became possible. Education, science, research, as well as entertainment, were placed on a novel, technically and content-wise revolutionary foundation.

Books continue to change society today. The technical possibilities of mass book printing led to a radical increase in titles in the 18th and 19th centuries. Nevertheless, the conditions were still very different from today: those who wrote a book back then often produced a life's work. This is reflected in the high quality of old books.

Unfortunately, books age. Paper is not made to last forever. Therefore, it is essential to preserve the knowledge contained in books and to make old books available in the highest possible quality at low prices.
