According to historian Eckhard Höffner (see SPIEGEL), the book production in Germany in the 19th century was much higher than in France and Britain. In 1843, in Germany 14,000 titles were print, in Britain only 1,000. Höffner, who teaches at Viadrina University of Frankfurt/O., says that this was caused by the long time lack of copyright law. Prussia introduced it in 1837, but due to the political division it was difficult to grand copyrights in all Germany then.
Reprinters made it possible for many people to have books, in comparison to Britain were rich publishers sold expensive copies to a small, wealthy audience. In Germany publishers came out with luxury editions for the upper classes and cheap ones for the masses.
