debkellie - there is a mechanism to request that books are added to the EYB Library. You import the ISBN in the Import Books feature, which you access by clicking the My Bookshelf tab at the top. This is explained in our Help section - Can I get a book added to the EYB Library?
If we are unable to import the data from Amazon for the book you request, then we are not able to add it at this time. However, if it is a book that you want to index, then we will add it manually. Send us a request to [email protected] - please send ISBN if there is one, book title and subtitle, author, publisher, publication date, format, # of pages and if possible, the cover image (don't worry about cropping or size as we can fix that).
