In Latin American comparative politics, a tension exists between North Americanization and parochialism. While certain academic scholarship is published in Scopus-indexed journals that engage with “mainstream” Global North literature, other works are found in non-indexed outlets, focusing solely on their home countries and fostering parochial scientific communities. To assess this tension in graduate program curricula, we compiled an original dataset of comparative politics readings from 21 universities across nine Latin American countries. Our network analysis reveals a centralized structure influenced by mainstream readings, challenging the expectation of parochialism. In addition to the mainstream content, universities tend to incorporate readings from regional journals to facilitate cross-case comparisons. However, these materials are inconsistently shared, resulting in fragmentation of content from Latin American sources. Our findings contribute to and challenge the North Americanization versus parochialism debate, showing that future scholars receive similar mainstream training but encounter diverse regional materials during their PhD studies.
