 Hello friends, in this video I am going to deal with a secret topic in research and this is going to be a controversial topic also. I am dealing with this topic just for your awareness, for educational purpose only. According to your legal situations, you need to follow your country's law. So before going to the secret, I want you to understand about the process of research. In process of research wherein the authors write the paper, send it to the publishers who owns the journals and after publishing the journals, they give the institutional access if they pay the money and these institutions give access of reading to the individual authors. So that is the usual research process. Before 1990, this was in position for every research process. Then during the end of 1980s and the beginning of 1990s, the open access system came into play. In order to maintain this journal, the publishers charge a minimal amount to maintain the journal and when they submit it, they collect it as publication charge and these journals can be openly accessed by anyone in the scientific society and they can access it freely. This model was called as open access model. Even though this model eliminated the need of lots of money paid by the institutions and if the individuals want to access directly also they need to pay a large amount of money. So this was abolished with the open access system. But the problem with this open access system is later the predatory journals appeared where they displayed false credentials and collected many articles. So this is about open and closed access system. So you need to understand before going to the piracy of the articles. So how an article can be pirated is these are all the publishers. So when the authors submit, they will not pay any publication fee. Instead of institutions paying the money, there are some piracy sites which takes the articles from the publishers, infringing the copyright law and distributed to the other authors. The leader in this piracy work is Sky Hub. So let us see about the Sky Hub usage around the world. So these are all based on the downloads which is happening around the globe. So this is the Sky Hub usage. As per the 2018 data, nearly there are 7 lakh articles downloaded per day. Sky Hub has a database of nearly 95% of all scientific articles that is about 9 crore articles. The mastermind behind the Sky Hub is Alexandra Elbakind. She is called as a Robin Hood of research. So she has taken the access of high cost research to the poor people who are doing research. So many people have nominated her for prestigious awards in research. Some have mentioned that she should also receive Nobel Prize also and some research scholars honoured her with naming the species which they discovered in her name. So there has been four species which has been named in order to thank Alexandra Elbakind, the founder of Sky Hub who made the high cost research accessible to the poor. She successfully conducts Sky Hub for 11 years. After legal notices, this domain kept on changing. So I am going to show how to use this Sky Hub and this is for educational purpose only. And you have to obey the law according to the country where you are staying. So now I am going to show this. So if you type Sky Hub Chrome Domains, it will take to the recent Sky Hub Domains. So this is available here. So you can access at skyhub.org, skyhub.azda, libgen.tw, skyhub.do are available. There are some other backup servers also which you can access. And there are Google Chrome extensions available. There are Sky Hub Master and Sky Hub, this is the Sky Hub Master with the growth line. And this is the Sky Hub Searcher. This is how the Sky Hub looks like. This is the database. It is available in English, Chinese, Russian and Portuguese languages. So currently there are about 9 crore articles available. 95% of the DOI that is Digital Object Identifier articles are available in this platform. Everybody can freely download this. And the amount which they are getting as the donations will be used for legal fee. Currently .se is the domain which is used. So if we type any DOI or PMID or URL, then you will get the access. For example, this article is a paid one. So if I am copying this link and pasting it in Sky Hub, then automatically this article will open. And remember, Sky Hub is only for the journals not available for books. So then how to use this Chrome extensions? So you have Sky Hub Searcher and Sky Hub Master. So Sky Hub Searcher, if you click, you need not bother about the domains. If the domain is blocked, you need not bother. If you click on this, automatically it will take you to the Sky Hub domain which is currently active. So that is the purpose of this Sky Hub Searcher. And you have Sky Hub Master extension. So when you open this article and you find that this free article version is not available, if this download, if you click on the download, it will ask for payment. So what we can do here is, if we click on this Sky Hub Master, then automatically it will take to the page where you can readily download the article. That is the use of Sky Hub when you need desperately article. You can try this mode, follow the legal restrictions also and copyright infringement also should not be there. There are always mixed opinions about the functioning of this Sky Hub, but it has crossed successfully 11 years with the legal fight. Hopefully, we wish that Sky Hub also successfully come out of this legal fight. And the vision of making the access to the poor researchers should continue legally in a bigger way. We wish that should happen soon. And the publishers also should come to an agreement or a solution for this problem. Thanks for watching this video.
