Obsolescence of physics literature: Exponential decrease of the density of citations to Physical Review articles with age

Author

  • Usha Gupta

Abstract

A synchronous citation study of 15 leading physics journals has been performed to determine the obsolescence of Physical Review articles with age. The density of citations to Physical Review has been found to decrease exponentially with a half‐life of 4.9 years, which is the first conclusive evidence of the exponential decrease. © 1990 John Wiley & Sons, Inc.
