What are PIDs?
PIDs are unique alphanumeric codes assigned to digital objects, such as research papers, datasets, and other academic resources. Unlike URLs, which can change over time, PIDs are designed to remain constant. This permanence makes them invaluable for citation, data management, and the integrity research outputs. Examples include Digital Object Identifiers (DOIs) for articles and datasets, ORCID IDs for researchers, and International Standard Name Identifiers (ISNIs) for authors and contributors.
Why are PIDs Useful?
1. Stability and Reliability: PIDs ensure that digital resources can be reliably located over time; a DOI will always direct users to the current location of an article, even if the website changes or the article is moved. This stability is crucial for the continuity of academic citations.
2. Enhanced Discoverability: PIDs enable more efficient searching and retrieval of academic resources. Search engines and databases use PIDs to link related works which enables ’citation chasing’, particularly in Scopus, Web of Science and Google Scholar.
3. Efficient Data Management: PIDs help libraries manage data, providing a consistent and standardized method of identification. This consistency aids in cataloguing, archiving, sharing data and the curation of data made in preparation for REF submission.
4. Improved Attribution and Recognition: ORCID IDs provide a unique identifier for researchers, ensuring proper attribution of their work. This helps in building a researcher’s professional profile and assists the tracking contributions and collaborations accurately.
Resources for Future Research
For those interested in exploring PIDs further, there are numerous resources available:
1. ORCID (orcid.org): ORCID provides unique identifiers for researchers, facilitating proper attribution and reducing the risk of name ambiguities.
2. DOI System (doi.org): The DOI system offers detailed information on how DOIs work and how they can be used to identify various types of digital content.
3. ISNI (isni.org): ISNI offers identifiers for individuals and organizations involved in creative activities, including researchers, authors, and institutions.
4.Jisc (jisc.ac.uk): Jisc provides a wealth of resources and support for the UK higher education sector, including information on the implementation and benefits of PIDs in scholarly communications.
5. DataCite (datacite.org): DataCite focuses on the assignment and management of DOIs for research data, supporting data sharing and citation.
PIDs are more than just technical tools—they underpin the integrity, reliability, and discoverability of research outputs. As the HE sector in the UK continues to embrace digital transformation, the role of PIDs will only become more critical. By understanding and leveraging PIDs, research libraries can enhance their support for academic research.
