This latest volume in the series of Merton Annals covers a turbulent time in the college's history, including the siege of Oxford. This volume continues the series of Merton annals published by the Oxford Historical Society, beginning in 1483. This volume, dealing with the main part of the seventeenth century, contains both a transcript of the (mainly Latin)register, and a long introduction discussing college development in this very disturbed period, culminating in Civil War, the siege of Oxford, and the imposition of Cromwellian government on the university.
