informationen aktuelle » informationen visuelle, annotationen aktuelle, informatik aktuelle
informatik kulturelle » informatik aktuelle, formate kultureller, informatikkultur neu
"informatik modell" » "information modell", "informatic model", "informatic models"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("informatik modell") OR ("((informatik kulturelle) or (informationen aktuelle))")).
• Removing quotes may allow a broader search: (( informatik modell ) or ( ((informatik kulturelle) or (informationen aktuelle)) )).
• Adding a wildcard symbol may retrieve word variants: (("informatik modell") or ("((informatik kulturelle) or (informationen aktuelle))"))*.
