There are many links you can click on throughout the document. Some will take you to other web sites (such as links to cities and ships) and some will take you to full size images on this web site. If the mouse cursor is a small magnifying glass, click with it anywhere in the document to display a larger image.
All the external links were working at the time of the last update of this document. Please advise me if any become inoperative (using the "Contact Us" page).
