The statistics give the number of downloads of PDF files with status codes 200 and 304 in the logfiles, according to the rules of the COUNTER-Project (COUNTER = Counting Online Usage of Networked Electronic Resources). Robots listed at http://www.robotstxt.org/db.html are excluded from the statistics.
Only the first author will be listed due to lack of space. For the same reason the title will be shortened to 120 characters.
