Starting research on Washington Treaty cost savings

Where can a researcher start looking for material on government cost savings in the Washington Treaty era?

Begin with Leo Marriott and John Jordan, then use their references and names to locate relevant articles and assess them critically.

The recommended books were a starting point rather than a complete answer on cruiser costs. Their references supplied names and search terms that could be followed into journal databases and related scholarship. Some of the resulting articles were not specifically about cruisers, but contained economic evidence relevant to the treaty-era question. Checking that material with an economist added outside disciplinary expertise to the reference-led research.
