As noted earlier, a DAISY DTB should reflect, as closely as possible, the original print publication. This cannot be overstated. The type of book in and of itself will in part determine the amount of structure and what type of DAISY DTB is most appropriate. For example, a mass market novel rarely contains much structure, can generally be enjoyed by an end user with the limited structure present in the print publication. The more complex a print publication is, the more complex the DAISY DTB is likely to be (if it indeed reflects the print). A print publication intended to be used as a reference book, will need to be produced so that the DAISY rendering affords the end user parallel access to the information contained within it.
