    What users do with PLOS papers Article-Level Metrics for 57,527 PLoS papers published until August 8, 2012. HTML pageviews and PDF downloads from PLoS journals website. 0.3% 100% 22.7% Citations are only a small fraction of how a paper is reused Article-Level Metrics collected August 8, 2012 for 57,527 PLOS Papers
  5. 5 The PLOS Article-Level Metrics project started in 2009 and

    tracks usage, citations and social web activity for all PLOS articles.
