ArXiv is for pre-prints. These are papers that have not yet undergone peer review. There is also bioRxiv, medRxiv, and others that are for specific field. SciHub is a piracy site for downloading papers. It is very useful, even when you have “legal” access to papers, because you can quickly load a paper using its DOI.
What’s the difference between scihub and arvix? I have heavily used arvix for my thesis and this is the first time I hear about scihub.
