Design of the footnotes
General aspects
- Footnotes appear in superscript Arabic numerals.
- Footnotes are numbered on each page anew when they appear at the bottom of the page (=> recommendation).
Alternative: Footnotes can be listed at the end of chapters or the paper. Then they are numbered consecutively.
- Footnotes are treated as complete sentences, i.e. they begin with an uppercase letter and end with a full stop.
- When reproduced in the same sense, a "siehe" is placed in front, when quoted verbatim, the name of the author.
- A repeated citation of the same source can be done with "ebenda". There must then be a direct reference to the author.
- In the case of sources that concern several pages, please refer precisely to individual pages or passages.
- Please do not include explanations and contents in the footnotes, but use them only for source references.

Procedure for indication of sources
There are 2 methods to indicate sources. The classical method is also the more comprehensive and follows the rules in the literature list (see section 1.5). Since the detailed information appears in the bibliography anyway, only the more recent procedure is presented here. The same procedure is to be followed for Internet sources.
- Usually the name, the year of publication and the properties are required for the verification.
Example: Homann (1992) S. 12-15.
Example: Homann (1992) S. 12-15: Homann (1992). (Only for short articles without page reference!)
- In the case of authors with the same name, the first name is written out as a letter or in full
to be included.
Example: K. Homann (1992) S. 12-15.
- If there are several contributions in the year of publication, they should be listed in the order of publication
to differentiate. Example: (1992); (1992a); (1992b)
- If the name given is the publisher, this must be noted.
Example: Homann (Hrsg.,1992) S. 12-15.
- The title of the book is to be mentioned if the author is mentioned several times on one page with
is cited in different books.
