  • In a classic paper by the late Yale historian of science, Derek De Solla Price (1965), based mainly on the study of citations in a single scientific research field, it was shown how citations in a developing research area have a strong 'immediacy effect'.1 Citation was found to be at a maximum for papers about two-and-a-half years old, and the 'major work of a paper ... [is] finished after 10 years', as judged by citations.

When it was published, it became a useful guide for both “seasoned” cryobiologists and those who had just started their journey to this fascinating science.
