The ISBN for the reprinted (2012) edition by Seaforth Publishing is: 978-1-8432-149-6
It looks like 'Grand Fleet' which covers 1906-1922 has also been republished. ISBN 978-1-84832-085-7
I have access to an ebook version of Grand Fleet via an academic book site via my university, indeed it looks equally as good, but I never seem to get time to read to read much while on the PC these days and I haven't got the rights to download the entire thing, only page PDFs.
