Selected outlets include:
Also available in shops and outlets across Islay including the Bridgend shop, the Nature Centre in Port Charlotte and the Bruichladdich mini-market.
A new Volume II was published in April 2021. It included four new excursions on Islay, plus 6 on Jura and 3 on Colonsay. It is now discontinued and has now been superseded in 2025 by two new Guides to the Geology of Jura and of Colonsay.
