The identification of this core collection was based from their use made by the academic community: “where they publish”, “references they cite” and “journals where they cite them”. The analysis considered several aspects such as: area of study, level or quartile, impact factor, subscription cost, type of access, as well as the UNAM departaments that subscribe to them. A period of 40 years was covered and the international journals indexed in the Web of Science were considered. The results identified more than 5 000 titles used by the academic community throughout its history. The core collection consists of 68 titles, representing 1.36% of the total, with an approximate cost of $ 287 832 USD. 45.58% of this collection was located in the first quartile of its corresponding area and 14.70% of the subscriptions have duplicates in other departments of UNAM.

La identificación del núcleo parte del uso que realiza la comunidad académica: “donde publican”, “referencias que citan” y las “revistas en donde los citan”. El análisis consideró aspectos como: área de especialidad, nivel o cuartil, factor de impacto, costo de suscripción, tipo de acceso, así como dependencias que las suscriben en la UNAM. Se cubrió un periodo de 40 años y se consideró a las revistas internacionales indizadas en la Web of Science. En los resultados se identificó más de 5 000 títulos utilizados por la comunidad académica a lo largo de su historia. El núcleo básico se conformó de 68 títulos, que representó el 1.36% del total, con un costo aproximado de $287 832 USD. El 45.58% del núcleo se ubicó en el nivel 1 de su área y un 14.70% de las suscripciones se duplicó en las dependencias de la UNAM.
