well that is very disappointing. i added the book to my wish list but didn't buy it yet, so i guess i will wait... in the meantime, it's far less convenient but it might be useful to you as a reference, have you seen this site ?
http://www.bartleby.com/113/ it presents the complete poems of Emily Dickinson online. i'm not sure whether these are the original poems or the "arranged" versions, but you might want to take a look just in case... at the very least, if you plan to do extensive editing of your epub version, it might help you there ; they seem to have taken a bit of trouble with the formatting.
