http://journal.fi/virittaja/article/view/40155 isn’t available Open Access because viewing the PDF is only possible with a login. And you need to see the PDF because the e-text is lacking the German UMLAUTE (ä, ö, ü). It is not clear if the text on the page is the whole text of the article, but in the case of http://journal.fi/virittaja/article/view/52698 (2016) it is clear that only the abstract is free. “Virittäjä” is a subscription journal.
Some journals are Open Access, some not.
