Grey (or gray) literature – 'grey lit' for short – includes such forms of communication as reports, white papers, dissertations, newsletters, slide decks, blogs, and podcasts. The Grey Lit Café explores the opportunities and benefits that grey lit provides for professionals and researchers. The podcast is directed by Anthony Haynes, produced by Dr Bart Hallmark, and published by Frontinus Ltd, a communications agency focused on engineering, infrastructure, sustainability, and research. Frontinus provides consultancy, editing, writing, and training services. If you're creating some grey literature and would like some support, contact us via our website, frontinus.org.uk.
