Hello, I noticed that apparently all CiteSeerX URLs (under https://citeseerx.ist.psu.edu/ or https://csxstatic.ist.psu.edu/) redirect to a Wayback Machine page corresponding to the original URL. Unfortunately, many of the pages aren't saved in the Wayback Machine, and even those that do exist seem to be broken (example).

Has something happened to CiteSeerX? I couldn't find any related announcement on the Wayback Machine copy of the homepage or anywhere else (e. g. somewhere on https://ist.psu.edu/).

   Oh wow. This is terrible news. Somebody please tell me that there is - or can be - some sort of focused effort to move all the CiteseerX content over the Wayback Machine if CiteseerX is truly gone. I'm happy to volunteer if there's any avenue to help out with such an effort.

   I get that the funding climate is difficult, and keeping projects like this going is really quite hard, but some kind of upstream notification at least acknowledging what happened would be very helpful. (And now it has been three months!)

   Hi! I am sorry for the late response. CiteSeerX is working with Internet Archive and Amazon to migrate the full text to permanent locations. Our process is slow due to limited time and resources, but we plan to make all PDFs available on the Wayback Machine. We thank you all for using our service in the past years.

   Thank you for the response and for all the work maintaining CiteSeer over the years. It will be really great for the community when the migration is done!
