Usage tips
Compound word
This word is made up of 'die Information' (information) and 'die Quelle' (source). So it literally means 'a source from which information comes', which makes the meaning very transparent.

The internet is a huge, but not always reliable, information source.
Typical collocations
Common adjectives are 'zuverlässige' (reliable), 'sichere' (secure/safe), 'glaubwürdige' (credible), or 'anonyme' (anonymous) information sources. Typical verbs are to 'nutzen' (use), 'prüfen' (check), 'angeben' (state/list), or 'zitieren' (quote/cite) an information source.
EXAMPLE
Für eine wissenschaftliche Arbeit muss man alle Informationsquellen genau angeben.
For an academic paper, you must list all information sources precisely.
Use in context
The term is especially important in journalism, academia, and any kind of research. Correctly evaluating and citing information sources is a key skill there.

Informationsquelle vs Quelle
source
'die Quelle' and 'die Informationsquelle' can both mean the place or person from which you get information. 'die Informationsquelle' is more specific and immediately makes it clear that it is about knowledge or news. 'die Quelle' is shorter and very common, but it can also mean water, energy, or an origin. For this reason, learners may confuse the words. If the context is not clear, 'Informationsquelle' is clearer; in texts about research, 'Quelle' is often enough.
Informationsquelle

Quelle
