Endogenous retrovirus (ERV) research amalgamates host-retroviral coevolutionary, phylogenomic, infection, immunity, and cellular studies in various hosts ranging from fish to humans. Henceforth, a bibliometric analysis of these publications may aid in the identification of trends in ERV research. It was the foremost bibliographic study, with the key aim to conduct the bibliometric network analysis (e.g. co-authorship, co-occurrence, citation, bibliographic coupling, and co-citation analysis) to find the most prolific authors, organizations, and countries in ERV research, based on the mapping of bibliographic data. Second, the mapping based on text data comprised to chalk out the research trend over the time. The global literature about endogenous retroviruses published between 1985 and Sep 2021 was searched in the Web of Science (Core Collection) database using the "ENDOGENOUS RETROVIRUS" keyword. The bibliometric analysis of this dataset was carried out using VOSviewer version 1.6.17. According to findings, English was the de facto language of these publications, and 2157 were original articles. Among 2939 published documents, "endogenous retrovirus" was the most frequent keyword. Moreover, it revealed the United States as a core contributor to studies on the ERV. The Journal of Virology published a substantial amount of manuscripts in ERV. Robert Koch Institute and Harvard University were leading organizations for research in this field. The application of ERV research from China could be the research hotspot to follow in the coming years. Current bibliometric analysis provides a comprehensive picture of ERV research progress and has highlighted the contribution of different stakeholders.
内源性逆转录病毒（ERV）研究融合了宿主与逆转录病毒的共同进化、系统基因组学、感染、免疫以及细胞研究，涉及从鱼类到人类等各种宿主。此后，对这些出版物进行文献计量分析可能有助于确定ERV研究的趋势。这是一项最重要的文献研究，其主要目的是进行文献计量网络分析（如共同作者、共现、引文、文献耦合和共被引分析），以便根据文献数据的映射找出ERV研究中最多产的作者、组织和国家。其次，基于文本数据的映射旨在勾勒出随时间变化的研究趋势。使用“内源性逆转录病毒”关键词在科学网（核心合集）数据库中搜索了1985年至2021年9月期间发表的关于内源性逆转录病毒的全球文献。使用VOSviewer 1.6.17版本对该数据集进行了文献计量分析。根据研究结果，英语是这些出版物的实际语言，其中有2157篇是原创文章。在2939篇已发表的文献中，“内源性逆转录病毒”是最常见的关键词。此外，研究表明美国是ERV研究的核心贡献者。《病毒学杂志》发表了大量关于ERV的手稿。罗伯特·科赫研究所和哈佛大学是该领域的主要研究机构。中国的ERV研究应用可能是未来几年值得关注的研究热点。当前的文献计量分析全面呈现了ERV研究的进展，并突出了不同利益相关者的贡献。
