Scotland: Myths & Legends, by Beryl Beare. 1996. Lomond Books. 80 pages.

At 80 pages, and with a plethora of color photos, this is no definitive collection. But it has small sections on:

Legends of the Lowlands
Abbeys
Castles
Cities
Loch Lomond, Fife & Arran
Aberdeen
The Heart of Scotland
Macbeth Country
The Great Glen
The Highlands
The Legends of Skye
Mull, Iona & Islay
Legends of the Western Isles
Shetlands & Orkney.

It's an amusing little book, one which can get one plotting to do more in-depth research into the legends herein referenced.
