The resulting data<ref xmlns="http://www.tei-c.org/ns/1.0" n="1" target="ftn1" />, which shows the publication of books in the German language, seems to be fairly representative of the general print production in Germany. After a relatively slow start up to 1520, the Reformation led to a very considerable spike in print production. The Thirty Years War (1618-1648) brought the print industry almost to a standstill. After that we see a steady rise in the number of editions per year, quickly accelerating at the end of the 18th century. Interestingly, the slight drop towards the very end of the century is rather unexpected. It may just be the result of the library’s preference to digitise material pre-1800.
