I am from a biomedical background. In the biomedical background, it is very easy to get a research article for free. If you search in PubMed, Scopus, or Web of Knowledge, you will find lots of papers thats you can read in full text. However, when i tried to find papers in the field of law, I found that all you had was Westlaw, Lexis Library, and Lawtel Heinonline. These are not free, you have to pay for them. Sometimes, you can find the odd abstact. Is there no free search database? I understand that all the papers will not be free; in the biological feild you will get a lot free, but some papers you will need to pay for.
To help in ansewring the question, I am not part of university, and only study UK law.
