Abstract

Presentation of Brooke's law for measuring the ageing of scientific literature was first introduced in 1970. Analyses 5 methods of statistical analysis based on this mathematical model: maximum citation, half-life, Griffiths' method, Brookes' graphical analysis and linear regression. Compares results from practical examples using each method, showing Griffiths to be imprecise and unstable, while the others produce similar results. Potential sources of error (size of sample and of age interval) can be readily controlled. An annotated bibliography is appended
