The book will appear in the two page view. Next, look to the right of the page for 4 arrows going in different directions and click on them. This puts you in whats called the full page view. In this mode you can zoom in or out by hitting the plus or minus controls. You can also change to the single page view by clicking on the single rectangle, 4 page view by clicking on the four squares or the two page view clicking on the two rectangles. 

Once you are in the full page view you can search within the book for a last name, first name or both. The search box should be in the upper right hand side.
