This is a textbook designed with iBooks Author. The original book features interactive elements such as slideshows, sliding content and pop-over footnoting. iBooks Author content is no longer supported by Apple, so presenting it online is a challenge. Click the link above to view the book in an HTML 5 player. This version does not include any of the interactivity from the original version. It is also only appropriate for fullscreen desktop viewing, as the width of the open book is fixed at 1800px. Smaller browser window sizes will need to decrease browser magnification.
Below are screen shots from the iBooks Author version, previously hosted on Apple Books.
