Sampling a decade of Brassey's Naval Annual

When an article cannot cite every volume of a long-running annual, a compact overview can be built from evenly spaced editions. This sample uses 1939, 1943, 1946, and 1949, with 1936 as the ideal additional prewar point. All four keep the same editor even though the 1943 volume has a different publisher. Three evenly spaced points or a denser five-volume pattern can serve different comparisons. The interval should remain consistent, while the number of sample years depends on the available space and the argument's needs.
