Assessing The Royal Navy and the War at Sea

How useful is The Royal Navy and the War at Sea, 1914-1919 as a reference?

It is likely well researched and valuable, as Mace and Grehan's work usually is, though their precise language can be demanding.

The Royal Navy and the War at Sea, 1914-1919 was introduced and compiled by Martin Mace and John Grehan. The volume had not been revisited recently, so the assessment draws on the authors' wider body of work. Their research and content are usually strong. Their pursuit of linguistic precision can make the prose demanding, leaving the material valuable but sometimes dense.
