All the maps on this site are presented using Zoomify software.

Zoomify no longer relies on Flash (an Adobe product), or on ActiveX (a Microsoft product).

When you look at a page on which a map is presented by Zoomify, you will see this set of controls at the bottom left corner of the map image. If you click on its double-right-arrow, you will "open" it and see ...

... this. (You may need to use your browser's vertical scroll bar to get to the bottom of the page.) You can:

• Click on the - sign to zoom out
• Drag the triangle right and left to zoom in and out
• Click on the + sign to zoom in
• Click on any of the four arrows to move the viewport over the map
• Click on the cryptic symbol including a ↖ to reset Zoomify
• Click on the cryptic symbol including a ↗ to go full-screen; and click on it again to return to a normal browser window
• click on the ? to get some help from Zoomify

• Click on the map to zoom in on a region centred on where you clicked
• Drag the map to see a different region of it
• In the small version of the map at the top left, drag the viewport to select a region
• Use the wheelie on your mouse (if you have one) to zoom in and out
