What would it be if all research was freely available? Within the Open access week you can try it with the Royal Society Publishing that made all it's content freely available until 6th November!
You can find their journals on https://royalsociety.org/journals/
Do you know the royal society? This is probably the oldest scientific company established in 1660. Its members were top scientists in history, like Isaac Newton, Louis Pasteur, Jan Purkyně or Albert Einstein. Publications issued by the royal society even today hold a very good impact and are frequently cited, even these in open access, e.g. Open Biology.
