The Oxford Companion to Scottish History interprets history broadly, including archaeology, architecture, climate, culture, folk belief, geology, and the langauages of Scotland. It covers more than 20 centuries of history, including immigrants, migrants, and emigrants. It extends from Orkney and Shetland to Galloway, the Western Isles to the Borders. It deals extensively with Scots abroad, from Canada to Russia to New Zealand. It includes entries on historical figures from Columba, Macbeth, and William Wallace to James (Paraffin) Young.
