In English, "information science" (http://en.wikipedia.org/wiki/Information_science) is usually more closely associated with classification and resource collection management, such as archival work and library cataloging.

I like "informatics" though. It is used in "bioinformatics", at least.

Even in England it used to be commonly called Informatics. I like Informatics/Informatik/Informatique etc. much better than "Computer Science", because most applications are not really about computing, but about information.

In danish computer science is called "Datalogi" (Data-logy; data as a subject of study)

True. When I lived in France it was l'informatique.
