A German thesis ends with a signed declaration. At the Goethe University in Frankfurt, students of the geosciences affirm that they wrote the work on their own and used keine anderen als die angegebenen Quellen und Hilfsmittel, no sources or aids other than those listed. Every passage taken from another text, wörtlich oder sinngemäß, word for word or in substance, must be marked as such. The University of Hildesheim asks for the source in jedem einzelnen Fall, in each individual case. The Frankfurt form now adds a sentence.
