|Sci Hub is a website that provides free access to scientific research articles and papers that are typically behind paywalls. It was created by Alexandra Elbakyan in 2011 with the goal of making scientific knowledge freely available to everyone. Sci-Hub bypasses traditional subscription and payment requirements by using a collection of login credentials obtained through various means. The website has gained attention and faced legal challenges for copyright infringement, as it allows users to access copyrighted material without proper authorization. Despite legal controversies, Sci-Hub has been widely used by researchers, students, and individuals seeking open access to scientific literature.
