A scientist asks questions, looks for solutions, studies similar cases, develops theories, strays, develops tools, conducts experiments, and repeats them many times. Other specialists verify their research. Eventually, after months, and sometimes years of work, they find an appropriate journal and publish results that shed new light on a problem. What is next? The publisher hides everything behind the so-called paywall, reaching several hundred zlotys for a single article. The consequence of the difficult access to knowledge is the ongoing institutional and guerrilla war for the opening up of science.
