This is important to some of us who do a frugal research. When I check online, I normally find abstracts but these do not provide the results. If we want them we have to pay, and we have no research grant for that. Sometimes, we manage to get a free full paper that may or may not be an empirical research paper. Reviewers may say that we only read the abstracts only, as if we are being lazy. They should be aware that unless the paper is free, we have a great problem. Do you agree?
And is there a minimal number of empirical articles we should cite?
