PARIS: US researchers show that changes in society and advances in understanding can breathe new life into sometimes long-forgotten science papers such as Einstein’s take on quantum mechanics.
The finding, published in the Proceedings of the National Academy of Sciences (PNAS), has implications for the increasing focus on citation impact as a basis for promotion, tenure, hiring decisions, institutional ranking and research funding grants.
Dr Alessandro Flammini and colleagues at the Centre for Complex Networks and Systems Research at the University of Indiana, show so-called “sleeping beauties” of the science world are more common than previously thought.
And increasingly papers that do gain a second life are being used in disciplines outside the field of the original paper.
According to the study authors, a sleeping beauty in science refers to a paper whose importance is not recognised for several years after publication.
Its citation history exhibits a long hibernation period followed by a sudden spike of popularity, the authors note.
For the study, the authors analysed the citation history of more than 22 million scientific papers published in all disciplines of natural and social sciences over a time span of more than a century.
The results show many sleeping beauties become highly influential more than 50 years after their publication.
