In version 6.0 of the dLibra system, there is a new function of presenting one object with the use of several presentation formats (the multi-format function). It can be used for presenting one object in various formats (for example, PDF, DjVu) or in various presentation versions (for example, PDF with a scan, PDF with a transcription, PDF with a translation). For more information about that topic, see chapter [EN] 04. Creating and modifying multi-format objects.
