Hardback book ‘Gaelic in Scotland 1698-1981: The Geographical History of a Language’ by Charles W. J. Withers, 1984. Foreword by Derick S. Thomson. Surprisingly little is known of the geographical history of Gaelic: where and when it was spoken in the past, and how and why the Gaelic-speaking area of Scotland has retreated and the language declined. This book answers four broad questions: what has been the geography of Gaelic in the past? How has that geography changed over time and space? What have been the patterns of language use within the Gaidhealtachd in the past? And what have been the processes of language change? Tiree mentioned pages 50, 68, 207, 221, 299, 311.
