While holding the left mouse button and dragging the cursor left or right, you can have a panorama view.
When you guide your mouse cursor over a hotspot, you get some brief informations. Most of the hotspots are linked to the next point of the virtual tour or more information.
Next to large stairway there are some book scanners in the Triplex Building. For free, you easily can do coloured, black and white, large and small scale scans and immediately save them on a USB-Stick or a memory card. A small manual is placed here too.
