Web of Science (ISI WOS) is quite an important database of sceintific papers. In addition it is connected with ebsco, jstor etc. Ergo, it is a great place where to start your research. I have prepared a video demonstrating some key functions of the database. Around 44:00-47:00 I struggle with one issue (so skip it if you want). Initially I wanted to cut these three minutes of my shame. Nevertheless as it is now, it shows where I did all the mistakes... and that failiures are a normal part of research.
