Following ideas inspired by Vannevar Bush's famous article As We May Think, Eugene Garfield at the Institute for Scientific Information in the 1960s undertook the development of a comprehensive index of how scientific thinking propagates. The creation of his Science Citation Index (SCI) had the effect of making it easy to identify exactly which scientists did science that had an impact, and which journals that science appeared in. It also caused the unexpected discovery that a few journals like Nature and Science were core for all of Hard science. The same pattern does not happen with the humanities or the social science - possibly because objective truth is so much harder to establish there.
Eugene Garfield has also coined the terme Obliteration phenomenon
