Some books have pages that are best viewed when rotated by 90 degrees right or left (i.e. clockwise or anti-clockwise). RotateBookPage makes this easy, right in the Google Books display of the book pages.
Step 1: Search for a book that has a page that needs to be rotated. For example: https://books.google.com/books?id=JS4QAAAAYAAJ&pg=PA25
Step 2: Click on the page to be rotated (page 25 in the example). Arrows in green circles ("rotation arrows") are displayed at the top-left and top-right corners of the page.
Step 3a: Click on the rotation arrow in the top-right corner to rotate the page to the right (i.e. clockwise).
Step 3b: Click on the rotation arrow in the top-left corner to rotate the page to the left (i.e. anti-clockwise).
Step 4: Click on the page again (when it isn't rotated) to remove the rotation arrows.
