Habe etwas gefunden: "In the United States, the United Kingdom and Scandinavia, titles are usually written top-to-bottom, and this practice is reflected in an industry standard;[19] when the book is placed on a table with the front cover upwards, the title is correctly oriented left-to-right on the spine. In most of continental Europe, the general convention is to print titles bottom-to-top on the spine." http://en.wikipedia.org/wiki/Bookbinding#Spineorientationandtitlingconventions
