The digital transformation of scholarly communication has changed the way libraries manage, preserve scholarly research and share it with the public. This research looks at three persistent identifier (PID) systems: the Digital Object Identifier (DOI), the Open Researcher and Contributor ID (ORCID), and the Research Organization Registry (ROR), which are necessary for a transparent and interoperable library infrastructure. Evidence from 2019-2026 shows how PIDs have changed from metadata tags to machine-actionable connective tissue that links researchers, institutions, publications, datasets, and funding. Findings from implementation studies at the global level show very diverse adoption of ORCIDs, between 41% and 89% among German research organizations, yet continued issues with metadata quality and PID literacy. This research identifies promising practices in Europe and Latin America, examines barriers, and proposes measures for libraries, universities, policymakers, and Library and Information science professionals.

翻译：学术交流的数字化转型已深刻改变了图书馆管理、保存学术研究成果并将其公开的方式。本研究聚焦于三种持久标识符系统：数字对象标识符（DOI）、开放研究者与贡献者标识符（ORCID）以及研究组织注册库（ROR），它们是构建透明且可互操作的图书馆基础设施的必要支撑。基于2019至2026年的数据，研究揭示了持久标识符如何从元数据标签演变为可机器操作的连接纽带，将研究人员、机构、出版物、数据集及资助信息有效关联。全球范围内的实施研究表明，以德国研究机构为例，ORCID的采用率差异显著（介于41%至89%之间），但元数据质量与持久标识符素养问题仍持续存在。本研究识别了欧洲与拉丁美洲地区的优秀实践案例，分析了相关障碍，并为图书馆、高校、政策制定者及图书情报专业人员提出了应对措施建议。
