This webinar begins with a brief introduction on the use of persistent identifiers in research followed by an outline of how UNSW has approached supporting discovery and citation of grey literature. #1: DOIs to support citation of grey literature 1 ) UNSW service for DOIs to support citation of grey literature Dr Daniel Bangert, Senior Data Librarian, Library Repository Services, UNSW Library At UNSW, grey literature materials are often important parts of the scholarly record which can contribute to research impact, and thus there is a need to make them discoverable and citable. After investigating various options, UNSW implemented a service to assign persistent identifiers in the form of DOIs to grey literature held in UNSW Library repositories. A set of conditions was developed to determine eligibility for a DOI and govern their assignment. Accompanying workflows were put in place to enable DOI requests from UNSW researchers and also meet the needs of researchers or administrators that produce grey literature on a regular and ongoing basis. 2 ) PIDs for research Natasha Simons, Senior Data Management Specialist, ANDS Natasha will provide a quick overview of PiDs for research and this webinar series, and then give an overview of the ANDS Guide to Persistent Identifiers
