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 created 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 a mission to preserve the knowledge recorded in books and to make old books available in the highest possible quality at low prices.
