This script adds download buttons on Google Scholar, Scopus and Web Of Science, which lead to sci-hub. In this way you can get free access to scientific papers even if you or your university can't afford their prices.
// @description:it Bypassa le richieste di pagamento per i documenti scientifici scaricandoli da sci-hub invece di pagarli qualcosa come 50 sacchi ciascuno. Questo script aggiunge i tasti per scaricare su Google Scholar, Scopus e Web Of Science, che indirizzano a sci-hub. In questo modo puoi ottenere l'accesso gratuito ai documenti scientifici anche se tu o la tua università non potete permettervi il loro costo.
