This paper examines research on article processing charges (APCs) to understand the extent of attention given by researchers and assess the status. The study analyses document types, source types, source titles, affiliations, and open access types of APC research. It also explores countries of researchers’ affiliations, volume and growth of literature, and visualizes keywords based on data from Scopus. . . . Many papers addressing APC were published in Green Open Access sources. Researchers from all subject categories in Scopus have contributed to APC research, but the major focus of research in the area is library and information science. Interestingly, researchers outside the field, notably from biomedicine and computer science, have also contributed significantly, reflecting interdisciplinary engagement.
