Citation

Please use this information for the bibliographic citation. It refers to the actual version of the data file. A citation for older versions may be found under 'Errata & Versions'.

This citation is composed of:
[Principal Investigators] ([Version Year]): [Title]. [Data Collector]. GESIS Data Archive, Cologne. [Study Number] Data file Version [Version Number], [DOI].

If there are many principal investigators a name for the group is used instead of the person names.
If person names are used, a maximum of 200 person names are stated, after that 'et.al.' is used for abbreviation. (Only 10 up to 2017-06-14)

The year refers to the data file and is taken from the date of the version, except
if the version date is empty or '2010-04-13'. In this case a special 'publication year' is used, if available. If not available 'n.d.' is stated, because not in all cases the original publication year is known.

In some cases the data collector is stated in addition.
