Rows in the maps are numbered 1 through 7, and columns are numbered A through D.
In the text of the
Guide to the Map, a link to the large map
looks like this: 5A.
Two addresses, as in 6A:7B,
represent the upper left and lower right panels of the area of interest. These links
will take you to the upper left panel of the areas they name.

To return to the small map, click on the large map.
In v. 3.0 or newer browsers, the background of both maps
should appear in pink, yellow, green and blue to help you keep track of
where you are in the map. If the background is white or gray in a v. 3.0 or higher browser,
increase the color depth of your computer's display, or turn on dither in the browser. You may
also select a different main page which displays the maps with a
plain white background if you prefer.
