Booth graduated from the Universities of Sheffield, King's College London and Liverpool where he was supervised by Professor A. R. Myers. In 2011 he was awarded the degree of Doctor of Letters of Liverpool University, in recognition of his research and publications in his specialist subjects.
Career
Booth was lecturer in History at University of Liverpool from 1972 to 2010. He taught medieval history to undergraduates, and trained archives students in medieval palaeography and diplomatic. During this time he taught and organised University Continuing Education courses in History and Local History in the North West. Several of Booth's classes formed themselves into local history societies, all of which have active publication programmes. He has served on the Councils of all of the regional local history societies, has been chairman of both the Cheshire Local History Committee and the Lancashire Local History Federation and was president and joint general secretary of the Chetham Society. From 2008 to 2011 he was co-director of the Arts and Humanities Research Council -funded project, "The Gascon Rolls, 1317–1468", jointly with Malcolm Vale of the University of Oxford. Booth is a fellow of the Royal Historical Society, and has acted as external adviser to University of Toronto Press and the Irish Research Council, and as a peer reviewer to the AHRC. Booth's research focus has been in the field of medieval Cheshire. His research into the financial and legal records of the county palatine has added to historical knowledge of the county, and called into question previous assumptions about agriculture, political disorder, and involvement in the royal wars in Wales, Scotland and France. In particular, he has asserted that the oppressive period of the Black Prince's rule, did not result, as had been generally accepted, the "great rebellion of 1353". Booth's work has influenced other medieval historians; for example his study of the Black Prince's state visit to Cheshire in 1353 enabled Professor Thorlac Turville-Petre to demonstrate that the Middle English alliterative poem Winner and Waster was based on the events of that year in Cheshire. Similarly, Professor Chris Given-Wilson has stated that Booth's research on the detailed working of the mechanism of Cheshire’s government in the 1350s and 1360s has made clear the unique roles of the prince’s two successive business-managers, Sir John Wingfield and Sir John Delves. Booth's research students have continued his work; for example, Andrew Tonkinson's monograph on Macclesfield in the later fourteenth century and the late Phyllis Hill's edition of the County Court of Chester Indictment roll, 1354 to 1377. A group of Booth's former adult students formed themselves into the Ranulf Higden Society, which hosts lectures by medieval historians, and also organises members into research groups which are working on publishing medieval documents. The first volume of these appeared in Life, Love and Death in North East Lancashire 1510 to 1537. In October 2012 the University of Liverpool terminated Booth's honorary fellowship because of remarks made by him on a social media site which were critical of the University. In 2015 Booth was in the news when he discovered the apparent first known use of a now commonly used expletive, within the name of one Roger Fuckebythenavele, in the plea rolls of the Chester County Court for the years 1310–1311.
