Data notes

  • "All-time" Twitter metrics (from Crossref) currently date back to February 2017. This is pulled from a different source than Altmetric, so their totals will likely be different.
  • Download metrics are updated for each paper about once every two weeks, which means there may be a discrepency between the totals reported by the preprint servers and the totals reported here.
