Idea for next book.

For my next book i  would like to make the subject about the different types of  animals there are. I want to try and make it into different volumes since i have the option to divide up the animals into endangered, extinct, land, air and sea creatures. I will add any image i can find within the book and then under that I can provide some information about that animal. I want to try and make the format of the book like we did for the our first book where we kept folding it. I wanted to use a larger type of paper for this though.
