Scholarly journals help you keep up-to-date with the latest research.
Note that different journals are more influential than others. One way of finding out the academic status of a journal is to look it up in Julkaisufoorumi's publication forum, where journals and other serial publications are ranked on a scale from 1 to 3.
You can also find out how often a journal's articles are cited (their impact factor) in e.g. Journal Citation Reports.
