Creative Book Builder app (paid app). allows you to create and/or assemble & publish ebooks for most readers, even iBooks & PDFs too. What I love is the ability to integrate images and VIDEO directly from the iPad. Plus you can import docs from Google Docs, epubs from GDocs & Dropbox, PDFs, and various upload options including the above, FTP, and WebDav. With the import features, students can use CBB to assemble and publish.
