Abstract

The average life is an indication of the reason of obsolescence of the scientific literature and allows to determine the age and the decline of the literature used in a certain area of knowledge. The purpose of this article is to discuss the complexity of the calculation of the average life when analyzing citations of books, due to the question of the meaning of a work considered classic in the scope of Information Science, Literature and Sociology, and present a proposal of calculation which takes into account the standardization of the year of the work cited. Based on this proposal, an empirical research was conducted that determined the average life of 5,178 citations from books present in 57 theses and 113 dissertations on indigenous education for the period 1996 and 2016, available at the BDTD / IBICT. The average life of the books in the Other Knowledge Areas is 18.70 years and 18.83 years in the Education Area. On the other hand, the calculations for the aging factor revealed a value of 0.964 for the Other Knowledge Areas, and the annual loss of current literature consequently reaches 3.6%, also repeating the same numbers in the Education Area, that is, the information is outdated slowly
