There are 1978 research articles that have been published by the United States National Aeronautics and Space Administration (NASA) available, free of cost, at PubMed Central (PMC). Titles include everything from the 2018 article “Seasonal energy exchange in sea ice retreat regions contributes to differences in projected Arctic warming” to the 1965 article “Nature of Particles Involved in Lipid Synthesis in Yeast“. For English-reading scientifically inclined minds this should be a treasure trove.
NASA is not alone in making such a contribution to Open Access. The European Union, by way of its ministers of Science, Innovation, Trade, and Industry, realized that the only way to aid future discoveries was by making previous research accessible to researchers of all kinds. Hiding data behind paywalls* can become expensive and difficult for cross-field researchers who need to go outside their specialized fields. Their solution was to create Horizon 2020, an open access site for scientific articles.
Scientific Research, Open Access Journals, The Royal Society and the Society for Phenomenology and Existential Philosophy (SPEP) are some of the other available open access sites. While Elsevier have plenty of paywall journals they also list a number of open access journals. Some of them are non-English ones. Unlike Google Scholar, Google Dataset Search-engine (GDS) links solely to open access articles. I sampled it, and it seemed to do what it promised, but it is difficult for me to say whether GDS did its intended job.
I am a fan of education, good education, that leaves us more knowledgeable about a topic rather than mired in old prejudices and attitudes. Before the need for more accessible articles became loud enough to be heard, the general public had a difficult time finding anything solid to base their opinions on. Now we no longer have that excuse.
*While I no longer pay to read the article, the authors (or institution behind them) pay to have them made open access.
