The introduction to the index reads "Page numbers in italics indicate illustration captions." This meant that many vessels were mentioned in illustration captions, but weren't actually represented in the illustrations.

So now, a page number in italics indicates that the vessel in question is shown in the image.

From the introduction to the index, "Unless otherwise mentioned, all ships and units are United States forces."
