Interesting article on open access journals
New principals for re-using open access published scientific material have been laid out by the UK PubMed Central Publishers Panel. The Statement of Principals will allow scientists and researchers to use published material themselves in databases and linking, which could lead to further scientific discovery.
Under the terms of the statement of principals open access published articles can be copied, and the text data mined for further research, as long as the original author is fully attributed. Re-use of the material must be for non-commercial purposes and cannot alter the moral rights of the original authors.
