Persistent Identifiers

A persistent identifier (PI or PID) is a long-lasting reference to a document, file, web page, or other digital object. It is linked to the current address of the metadata or content. Unlike URLs, persistent identifiers are often provided by services that allow you to update the location of the object so that the identifier consistently points to the right place without breaking. Persistent identifiers are available for people (e.g. ORCIDs), institutions (e.g. ROR), research outputs (e.g. DOI). There are also product identifiers for books (ISBNs) and journals (ISSNs).

Further information is available in the Library Guide on Identifiers and to request a DOI or ISBN please contact Trish Finnan, Digital Publishing and Data Management Librarian.
