A New Glossary of the Dialect of the Huddersfield District was written by Walter Edward Haigh (1856-1931), who had been the Head of the English & History Department at Huddersfield Technical College, and was published in 1928 by Oxford University Press.
The book is noteworthy for containing a foreword by Professor J.R.R. Tolkien, who would go on to write The Hobbit and The Lord of the Rings.
Under the terms of the Copyright, Designs and Patents Act 1988, the copyright of literary, dramatic, musical or artistic works in the United Kingdom expires at the end of the period of 70 years from the end of the calendar year in which the author dies.
The author, local academic Walter Edward Haigh, died in January 1931 and copyright on his works expired at the end of 2001.
The foreword written by J.R.R. Tolkien is likely protected by copyright until 1 January 2044.
