The first edition of this book was published in 1995, and covered around 1,700 castles and other sites. The book was very well received and sold out quite quickly. Only a paperback was produced. This was the first title published by Goblinshead.

ISBN: 9781899874002 (paperback)

The second edition, covering about 2,000 places, followed in 1997, also by Goblinshead. This also did very well (despite a notorious and embarrassing problem with the missing J Section), and also sold. Again the book was only issued in paperback.

The third edition took longer to produce, having expanded to some 2,700 entries, and was published in 2001. Both a paperback edition and a deluxe hardback edition were published by Goblinshead, the hardback also with a colour section. This third edition was the most successful yet.

The fourth edition was published by Birlinn, and ran to some 3,000+ sites, and was published as hardback with a dust jacket in 2006. There was no paperback edition, despite one being promised.

The move to Birlinn was bitterly regretted by the author.

The fifth edition happily returned to Goblinshead in 2015, and both deluxe hardback with 64 pages of colour and a paperback edition were published. Both editions of the book were completely sold out by 2019.

The new sixth edition was conceived in around 2022 but had a long gestation, covering more than 5,800 sites and greatly expanded.

Only a hardback edition is currently planned. Due June 2025.

ISBN: 9781899874637 (hardback)

The first book in the Viridian format, blending the fantastic, long-established format of the hardback book with all the best features of a website, in this case including a scaleable interactive map, library of extra illustrations, and linked visitor information.
