The Extraordinary Growing Impact Of The History Of Science

Recently, intrigued by the results presented by the Google team in Verstak et al. 2014. arXiv:1411.0275 we attempted to re-check the hypothesis in http://arxiv.org/abs/1511.08310. The Google team claimed that more recently written papers have a larger fraction of outbound citations targeting papers that are older by a fixed number of years, indicating that ancient papers are alive and well-loved and increasingly easily found, thanks in part to Google Scholar. In http://arxiv.org/abs/1511.08310 we show we show that the full picture is considerably more nuanced. Specifically, the fate of a fixed sample of papers, as they age, is rather different from what Verstak et al.’s study suggests: there is clear and steady abandonment in favor of citations to newer papers. The two apparently contradictory views are reconciled by the realization that, as time passes, the number of papers older than a fixed number of years grows rapidly.
