Each time you access the eTextbook, it opens to the page that you most recently viewed. However, if you would like quick access to another page of the eTextbook, you can bookmark that page.
To make a bookmark, you can either click on the bookmark icon near the top-right corner of the reading pane, or you can right-click anywhere in the reading pane, and then click on the Add bookmark icon in the middle of the menu.
Your bookmarks are saved in the Bookmarks section of the left pane. Each bookmark is listed with the page number as well as the date the bookmark was made.
