I have just started my Ms.c, and I'm now really starting to read publications, and I think that many times the link to a paper could make it easier to formulate and scope a question.
I guess that some publications are publicly available, while others may be only in a journal, and readers have to buy it. I have also seen links from google scholar to my universities library, which probably paid for having that article\a copy of the journal. So: How do I determine if its legal to publish a link to a publication\paper?
I will consider all answers as IANAL answers
