Multi-Document Ebook: can ebooks have more than one pdf?
I have an unusual question:
Is it possible to have more than one document for download when a customer buys a single ebook?
I mean that a customer will log on to my ebook page on Lulu, buy the ebook and when he goes to download it, there will be two PDFs. First the book itself and secondly the accompnaying notes.
I do not wish to combine these two for certain reasons.
Does anyone know? I would appreciate anyone's answer.
