It gets points for a sturdy binding and bright, full-page color photos that support the text, and including e-books as well as print books in both text and photos.  But it lost points for being about a rather boring topic that seems like a waste of money, since I think there are probably better ways to teach the parts of a book.  However, it still might have earned an “Additional Purchase” if it hadn’t also shown itself guilty of one of my biggest pet peeves when it comes to books for young children:  over-simplification to the point of untruthfulness.  When describing the spine of a book, it declares, “Hidden stitches hold the pages together.”  Yet that’s not always the case; sometimes staples or glue hold the pages together.  It claims that all books have barcodes on the back and tables of contents in the front, and that facts fill up nonfiction books, yet not all books have barcodes or tables of content, and not all nonfiction is facts.  This book is full of misinformation.
