Where to research Warspite's 1930s refit

Which sources are useful for researching Warspite's 1930s refit?

Start with Friedman's and R. A. Burt's books on British battleships, John Roberts's work on British warships in the Second World War, and the naval architects' reports.

Friedman's book on British battleships and R. A. Burt's work on the Second World War fleet provide broad design and refit context. John Roberts's survey of British warships offers another useful starting point. The naval architects' reports contain more direct technical material on the reconstruction. Reading across these sources helps separate a general class history from the details of Warspite's machinery, protection, and structural changes.
