NISO continues its Primer Series with the publication of Understanding Metadata by Jenn Riley, Associate Dean, Digital Initiatives at McGill University Library, Montréal, Québec, Canada. The guide, which Current Cites calls "required reading in library and information science curricula everywhere," offers a comprehensive overview of information about an item's creation, name, topic, features, and more. It updates NISO's 2004 advice on the subject and follows on the "Research Data Management" Primer published in 2015.
