German language course from wikibooks.org is the result of an ongoing collaborative effort of several authors and, therefore, it is being constantly developed and improved. The latest version of this course can be downloaded here, but the formatting of the PDF file seems a little bit odd and some lessons are not yet finished, so you may be better off using the original version from 2006 available under the link above. This course is suitable for total beginners to teach them basic grammar, phrases and vocabulary used in common, everyday situations，
