While I have relatively good access options through my university, roughly half of the publications appearing in my Google Scholar alerts are unaccessible. As they are also in fields were use of preprint services isn't common, it really interferes with me being up to date with ongoing research.

As the use of sci-hub is so common, I wonder about the wider implications of the newest articles being inaccessible. Could bibliometric methods be used to quantify this? Missed citations? Less citations for articles published in more obscure journals?

Interesting that no new solutions have come out yet. I'm seeing people getting back to use #ICanHazPDF - not the best way to conduct research when an article is often just a gateway to more finding more relevant articles to read.
