In addition to the Next and Previous buttons you may turn the pages by grabbing any corner with the mouse - try it - its fun!

The Zoom In button will bring up a magnifying glass which you may grab most anywhere and move it around the page. It will start at two times magnification but you can zoom it up to 3 with the sliding bar at the bottom.

You may also change the size of the magnifying glass by dragging the lower right hand corner.

You're loading a much higher resolution image when you use the magnifying glass so it may take a little extra time to load.

Close the magnifying glass by clicking on Zoom Out or the X in the upper right corner.
