The developments in the field of information technologies in the recent years have been so rapid that today the means of presenting books in digital form have improved in an incredible way, thus ensuring advancements in the quality of the digitisation. The prerequisite for this is the quality of the data sets and the scans, the latter depending very much on the quality of the scanners, their settings and the workflows in scanning mode. Besides, the quality of the records depends on several other factors. The orientation to international standards can certainly be counted among the most important criteria, but the granularity of the collected data is also an important basis for optimised visualizations. In the following, I will explain the current possibilities of visualisation by reference to the Digital State Library of Upper Austria DLOÖ. This contribution deals with precisely the above-mentioned factors as comprehensively as possible as well as with the resulting visual display options, without going beyond the scope of the publication.
