Dear Sir/Madam, Just to understand why we need Sci hub kind of tools to access information and how unrestricted access to knowledge is addressed previously. - Aaron Swartz and The Guerrilla Open Access Manifesto  Aaron Swartz was an Internet wizard who was behind the development of Creative Commons License and RSS Syndication. He took his own life in 2011. But what he did in a span of 26 years of his life was something very extraordinary and interesting. He was a fierce proponent of open access movement. He wrote the “Guerrilla Open Access Manifesto” to propagate free and unrestricted access to knowledge. Swartz did then what Sci hub is allowing us to do now. He downloaded millions of articles from JSTOR through MIT computer networks. The “Guerrilla Open Access Manifesto” reads like this “Information is power. But like all power, there are those who want to keep it for themselves. The world's entire scientific and cultural heritage, published over centuries in books and journals, is increasingly being digitized and locked up by a handful of private corporations….”. - Delhi University and Copyright Tangle with Major Publishers We all know how Oxford University Press, Cambridge and Tylor and Francis didn’t allow photocopy of the course materials they publish for students at Delhi University.  They filed a copyright suit against the sale of photocopy materials at Delhi University, however Delhi High Court dismissed this copyright infringement petition. This was done by the major publishers to restrict the access to reading materials. How many of them in a country like India able to afford thousands of rupees to purchase books and other reading materials? - German Researcher boycotting Elsevier Publications  Early 2017 some 60+ German Universities tried to cancel the subscriptions to Elsevier journals citing increasing costs. They demanded to make German publications open Access. German Universities wants their research publications available openly for them to access without paying exuberant fees to access their own published materials and others. This was an interesting developments in journal subscriptions and pricing models. There are other intricacies which is not needed here to discuss. But this issue brought up the debate on free access to knowledge. - Microsoft Windows Operating System and Piracy We are all familiar on this. Most of us are using pirated Windows OS for running other applications in our computers. Interesting fact is that except in few occasions Microsoft has never made this issue an important one and also there was no substantial information to claim that pirated Windows OS has lost their financial benefits considerably. Even at times we have heard that the company itself allow general users to have pirated Windows OS versions so that they will be familiar with this OS and help them to thrive their business in a different way. Today we can download songs and films of all kinds through Torrent. Is this legal or illegal? Today Internet itself at the centre of creating an unequal world which was not the vision of the creators of Internet. This is an unending question.              ------------------------- With best wishes Vasantha Raju N.Mysuru
