Sci-Hub has made nearly all articles freely available using a black open access model, leaving green and gold models in its dust.
Why, after 20 years of effort, have green and gold open access not achieved more? Do we need ‘tae think again’?
If human nature is to postpone change for as long as possible, are green and gold open access fundamentally flawed?
Open and closed publishing models depend on bundle pricing paid by one stakeholder, the others getting a free ride. Is unbundling a fairer model?
If publishers changed course and unbundled their product, would this open a legal, fairer route to 100% open access and see off the pirates?

The website Sci-Hub provides access to scholarly literature via full text PDF downloads. The site enables users to access articles that would otherwise be paywalled. Since its creation in 2011, Sci-Hub has grown rapidly in popularity.
However, until now, the extent of Sci-Hub’s coverage was unclear. As of March 2017, we find that Sci-Hub’s database contains 68.9% of all 81.6 million scholarly articles, which rises to 85.2% for those published in closed access journals.
Furthermore, Sci-Hub contains 77.0% of the 5.2 million articles published by inactive journals. Coverage varies by discipline, with 92.8% coverage of articles in chemistry journals compared to 76.3% for computer science.
Coverage also varies by publisher, with the coverage of the largest publisher, Elsevier, at 97.3%. Our interactive browser at greenelab.github.io/scihub allows users to explore these findings in more detail.
Finally, we estimate that over a six month period in 2015–2016, Sci-Hub provided access for 99.3% of valid incoming requests. Hence, the scope of this resource suggests the subscription publishing model is becoming unsustainable. For the first time, the overwhelming majority of scholarly literature is available gratis to anyone.
