It's very difficulte to accumulate those point the get important books :'(
I report the message by the personn so it was delete but i didn't get my points back...
Now the question !
1. The emergence of sci hub is really helpful. Maybe there is studies on this points btw It could be interesting.
2. For me the emergence of sci-hub definitely helped me. Without it I couln'd access to greats informations or books for my work as a clinical student. so it also help me professionaly
3. What is sci-hub¡¯s next plan? Do you have any good suggestions?
To put evereydocs validate on sci hub mutual aid on sci hub :)
4. Suppose sci-hub really stops working one day, what will you do?
Crying and looking for other siteweb like it. But i'm sure that people will fix sci hub if it's not working anymore. because lot of people are depending of it
