"Citation Amnesia: NLP and Other Academic Fields Are in a Citation Age Recession"

This study examines the tendency to cite older work across 20 fields of study over 43 years (1980–2023). . . . Our analysis, based on a dataset of approximately 240 million papers, reveals a broader scientific trend: many fields have markedly declined in citing older works (e.g., psychology, computer science). . . . Our results suggest that citing more recent works is not directly driven by the growth in publication rates. . . even when controlling for an increase in the volume of papers. Our findings raise questions about the scientific community’s engagement with past literature, particularly for NLP, and the potential consequences of neglecting older but relevant research.
