Elizabeth Solopova is a Research Fellow and lecturer of the English Faculty, University of Oxford. Her work has focused on Old and Middle English language and literature, and more recently on the text and historical context of the Wycliffite Bible. She has published on Chaucer, medieval maps, the language and style of medieval English poetry, English and Latin biblical and liturgical manuscripts, and the origin, production, dissemination and use of the Wycliffite Bible. She currently leads a group of scholars working on new editions of the Wycliffite Bible and closely related academic and liturgical texts.

Jeremy Catto (1939-2018) was Fellow Emeritus of Oriel College in the University of Oxford. A late medievalist with research interests in the history of scholarship, universities, heresy and orthodoxy, he was editor of The Early Oxford Schools (1984) and co-editor (with Ralph Evans) of Late Medieval Oxford (1992), the first and second volumes of The History of the University of Oxford. His published essays range in subject from the political thought of Aquinas to the theology of Wyclif, and also touch on patronage, preaching, and law, as well as 'practical Latin' and formal English.

Anne Hudson is a Fellow of the British Academy, Professor Emerita (personal chair) of Medieval English at the University of Oxford, and an Honorary Fellow of Lady Margaret Hall, Oxford. Her scholarship, recognized by many national and international awards, established the study of the Wycliffite movement as an academic field. In addition to foundational work on the texts published here, she has explored at length and in detail the writings of John Wyclif and his followers, including those in continental Hussite Latin manuscripts, and has researched and edited a number of extensive English texts, many of them based on Latin models. She currently collaborates with Elizabeth Solopova on the study and editing of the Wycliffite Bible and texts it inspired.
