By the way, on citeseerx the next step is to make the archived copies available via DOI links. I'm working on making DOAI.io more complete and linked from Wikipedia. See also   and relatedly (on how to make use of imperfect archive URLs) . --Nemo 17:09, 12 June 2016 (EDT)
Is this project still going? I seem to be unable to get any item from the tracker, also due to "Tracker rate limiting is active". --Nemo 13:30, 13 June 2016 (EDT)
Other PDF work
- The largest work indexing PDFs crawled by IA is https://fatcat.wiki/ (super useful for academic papers).
- Others focus on "policy" documents: https://overton.io/
