Progress on open access is slow. 6 or 7 years ago I wanted to read a couple of papers by Cayley, who died in 1895. These were published in the Transactions of the Royal Society--and paywalled. (Google Books had a few volumes of his collected papers available, but not the one I needed.) A few years ago, the Royal Society finally made papers published before the mid-20th century available for free, which is progress, but considering the public funding for the Royal Society, it's hard to understand why anything they publish is still paywalled for 70 years.
