The convergence of Libraries, Archives, and Museums (LAMs) has become a key component of the digital humanities field, with research focal points evolving alongside rapid technological advancements. This study aims to explore the trajectories and development trends of LAMs’ convergence within the digital humanities, addressing their critical role in knowledge organization practices and their impact on the ongoing digital transformation process. Drawing on relevant literature from Web of Science and Scopus, BERTopic and Dynamic Topic Modeling were applied to identify topics and analyze thematic evolution over time. The findings identify 32 research topics, which are grouped into four primary research directions: Engaged Knowledge Sharing, Digital Technological Competency, Cultural Digital Preservation, and Research & Sociocultural Impact. The analysis highlights how digital preservation and heritage initiatives enhance public interaction, facilitate knowledge exchange, and promote cultural awareness, reflecting the intersection of technology and culture. By integrating deep learning methodologies, this study addresses the limitations of conventional analytical approaches, offering novel insights into interdisciplinary collaboration and knowledge innovation. Furthermore, it delineates the transition from traditional to emerging technological paradigms within LAMs, exhibiting both homogeneity and complementarity. These insights serve as a valuable reference for institutions, researchers, and policymakers, informing strategies for digital adaptation and fostering more inclusive and efficient public cultural services.
