Despite a very large number of studies on the aging and obsolescence of scientific literature, no study has yet measured, over a very long time period, the changes in the rates at which scientific literature becomes obsolete. This article studies the evolution of the aging phenomenon and, in particular, how the age of cited literature has changed over more than 100 years of scientific activity. It shows that the average and median ages of cited literature have undergone several changes over the… 

The Effects of Aging on Researchers' Publication and Citation Patterns

Drawing on a sizeable sample of 6,388 university professors in Quebec who have published at least one paper between 2000 and 2007, the results identify two turning points in the professors' careers, showing clearly that productivity and impact are not a simple and declining function of age and that they must take into account the collaborative aspects of scientific research.

A citation-based cross-disciplinary study on literature aging: part I—the synchronous approach

We provide a view of the literature aging features in the sciences and social sciences, at different aggregation levels, of major fields, subfields, journals and individual papers and from different

The lengthening of papers’ life expectancy: a diachronous analysis

It is shown that life expectancy is extensively different from a corpus to another and may be either finite or infinite, meaning that the corpus would never be obsolete from a mathematical perspective.

Cited Half-Life of the Journal Literature

The trend to cite older papers is not fully explained by technology, but may be the result of a structural shift to fund incremental and applied research over fundamental science.

A model showing the increase in time of the average and median reference age and the decrease in time of the Price Index

This paper proves two regularities that where found in the paper Larivière et al. (2007) that the mean as well as the median reference age increases in time and the Price Index decreases in time using an exponential literature growth model.

Increasing life expectancy of water resources literature

In a study from 2008, Larivière and colleagues showed, for the field of natural sciences and engineering, that the median age of cited references is increasing over time. This result was considered

Modeling the obsolescence of research literature in disciplinary journals through the age of their cited references

There are different citation habits in the research fields that influence the obsolescence of the research literature. We analyze the distinctive obsolescence of research literature in disciplinary

Is the Year of First Publication a Good Proxy of Scholars' Academic Age?

Based on a sample of Quebec researchers for whom their year of birth, PhD year as well as the year of their first publication are known, this work studies the relationships among these ages with the aim of determining how theiryear of first publication can be used to estimate their ‘real’ age.



On Growth, Ageing, and Fractal Differentiation of Science

A novel model on the ageing of recent scientific literature is formulated, which reinforces the idea of science as a complex, largely self-organising 'cognitive eco-system' and refute Kuhn's paradigm model of scientific development.


The expression ‘half‐life’, borrowed from physics, has appeared quite frequently in the literature on documentation since 1960, when an article by Burton and Kebler on The ‘half‐life’ of some

Changes in the Use of Literature with Time--Obsolescence Revisited

Citation studies confirm the great variation in citation decay between subjects and types of article and also show that the sources used for citations affect the results of analyses.

Publication delays in the science field and their relationship to the ageing of scientific literature

An exploratory analysis of publication delays in the science field suggests that the cited half-life of references may be reduced with a factor of about 2 if publication delays decrease radically.

A new classification system to describe the ageing of scientific journals and their impact factors

In this article, ageing patterns are examined in ‘formal’ use or impact of all scientific journals processed for the Science Citation Index (SCI) during 1981‐1995 and a new classification system of journals in terms of their ageing characteristics is introduced.

A bibliometric study on ageing and reception processes of scientific literature

It was found that obsolescence of the social science journals in the set is slower than for the medical and chemistry journals, and ageing seems to be specific to the field rather than to the individual journal.

The Structure of Scientific Revolutions

A good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted,

On the influence of growth on obsolescence

This paper develops a formal model for the influence of growth on obsolescence and proves that, in the synchronous case, an increase of growth implies an increased of the obsolescences, while, on the diachronous case; exactly the opposite mechanism is found.
