Hello Unpaywall users,
Over the last two weeks, one of the largest repositories we index, Semantic Scholar, removed most of the articles it had been hosting. The end result for Unpaywall is that about 1 million formerly Green OA articles are now Closed. This is about 12% of all Green OA. We're working on finding new locations for as many articles as we can.
The total number of articles removed from Semantic Scholar was about 8 million, but most of them are still OA because we had other locations.

Hi Richard,Do you know why these articles were removed from Semantic Scholar?
Just to spell it out so it's clear in my mind, 8 million articles have disappeared from Semantic Scholar, most of which Unpaywall had alternative locations for and so which remain available as Green OA items, but 1 million are lost from Semantic Scholar and no alternative locations for these exist. And that 1 million represent 12% of all total global green OA?Have I understood your message correctly?
