In the ➔ GESIS Data Catalogue, numerous helpful documents can be found. Please note that these documents correspond to those on the ➔ "Downloads"- section of the data documentation website.

• Within the tab ‘Data & Documents / Questionnaires’ the original survey questionnaires for each wave can be found (including filter conditions, interviewer instructions, etc.). These files are only available in the original study language (German).

• Within the tab ‘Data & Documents / Other Documents’ there are some other useful documentations, including a ➔ general overview in pdf format and construct overviews for each survey wave (e.g. a ➔ pdf file of the first face-to-face survey wave), a documentation of changes between the different data releases (e. g. ➔ ZA6701_changes_in_v3-0-0.pdf) and the documentation of particularities on different constructs (e. g. discrimination, report cards, BMI; these documents are Technical Reports, see below).
