Click on a book page to get arrows in the upper corners for rotating the page in 90 degree increments.
Rotates selected pages in Google Books results. 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.
