Abstract
Gerontology is understood as an interdisciplinary approach that addresses the process of aging and old age. The present article characterizes the evolution of research in the gerontological field during the last 44 years through a bibliometric analysis of the works of greatest impact in the area. Ninety-four publications were reviewed from the main collection of the Web of Science (WoS) by Thomson Reuters in the period 1975-2018. The publications and their longitudinal evolution, the coupling of classic documents, research areas, authors and co-authors, journals and countries are analyzed. It is concluded that the United States is the country with the largest number of publications, citations and journals disseminating classical texts.
