The maps were scanned at 400 dpi and saved as tiff files. These were converted to run on the Web under a program called Zoomify. You need Flash to take advantage of this software. To zoom in and out, use the scale bar to the left of the Zoomify screen or click on the map to zoom in. To move around, hold the left mouse button down and drag either the location rectangle or the map itself. To see a larger image, click on the "Click here for full screen" button on the top left of each page. You may need to be somewhat patient in using this software. In particular, wait until the image comes into focus before attempting a new command.
