The Royal Society announces their archive of 350 years of articles is freely available through the end of the calendar year. From the front page:

For the first time the Archive provides online access to all journal content, from Volume One, Issue One in March 1665 until the latest modern research published today ahead of print. And until December the archive is freely available to anyone on the Internet to explore.

Spanning nearly 350 years of continuous publishing, the archive of nearly 60,000 articles includes ground-breaking research and discovery from many renowned scientists including: Bohr, Boyle, Bragg, Cajal, Cavendish, Chandrasekhar, Crick, Dalton, Darwin, Davy, Dirac, Faraday, Fermi, Fleming, Florey, Fox Talbot, Franklin (pictured), Halley, Hawking, Heisenberg, Herschel, Hodgkin, Hooke, Huxley, Joule, Kelvin, Krebs, Liebnitz, Linnaeus, Lister, Mantell, Marconi, Maxwell, Newton, Pauling, Pavlov, Pepys, Priestley, Raman, Rutherford, Schrodinger, Turing, van Leeuwenhoek, Volta, Watt, Wren, and many, many more influential science thinkers up to the present day.

Here's a link to Crick and Watson (1953) whose innocent sounding abstract is as follows:

This paper describes a possible structure for the paracrystalline form of the sodium salt of deoxyribonucleic acid. The structure consists of two DNA chains wound helically round a common axis, and held together by hydrogen bonds between specific pairs of bases. The assumptions made in deriving the structure are described, and co-ordinates are given for the principal atoms. The structure of the crystalline form is discussed briefly.

I wonder if there is an article describing the discovery of dirt. That was tongue-in-cheek, the archive is an amazing browse.
