Information sources contain information for different needs:
Next step: Evaluate information and think about source criticism!
The source is of high quality if its content is appropriate, up-to-date, unbiased and comprehensive enough. Prefer original sources, not the bulletins or summaries of them..

You can also use data (e.g. dataset or datafile) as a source of information, for example research data collected by someone else or open data generated by some public organization. The data must also be cited to so that others can find the material and the data maker gets a merit from the use of their data. Learn how to refer to data, for example, with the guide from Aalto University.
