The GESIS data catalogue provides complete ISSP data and documentation materials, including variable reports/ codebooks, basic questionnaires (in English), and country specific materials as printable PDF files. Downloads are available free of charge after registration.
In addition to the data access, the GESIS data catalogue offers study descriptions containing substantial and methodological information. Each data set version has a unique persistent Digital Object Identifier (DOI) which is an important element for the correct citation of a data set. Errata are always assigned to a data set version and need to be taken into consideration when analyzing this data. For errata and version history, please see the study description, section 'Errata in current version', of the corresponding dataset.
