The site structure is complicated but advanced search features and some helping tools are provided. Online transactions facilities are also provided.
Different possibilities for searching and inquiring, i.e. the free text search for the whole GESIS or only its English part, or the search facility by area, topic or database
Advanced search facilities for the different ZA databases and catalogues. In many cases, the search option is only available in German
Clickable site map for the whole Gesis website. There is also a sitemap and an help file with detailed explanations about whole site use
Very deep and nested website, with the three constituent parts of Gesis (IZ, ZA and ZUMA) internally linked and not logically and graphically separated. It is quite easy to get lost also for an expert user
