On Friday, 22 January, the Digital Scholarship Team at the British Library held their first 21st Century Curatorship talk of 2021; Identify Yourself: (Almost) everything you ever wanted to know about persistent identifiers but were afraid to ask. This series of professional development talks and seminars is part of Digital Scholarship Staff Training Programme. They are open to all British Library staff, providing a forum for them to keep up with new developments and emerging technologies in scholarship, libraries and cultural heritage.
