The 006 and 007 fields display in Connexion just the subfields contents.
At times, it would be beneficial to have quick access to what the coding defines.
I encountered an audiobook on CD bib record that had a 006 field for computers.
It would be very helpful to have a way to examine the coding in this field (and the 007 at times too) to understand quickly the need for this field or to check the coding matches the item being cataloged.
The 006 provides a way to communicate additional components of the item. In this case, it "includes page turn track". I seldom find this feature on audiobooks. A chime was frequently on audiocassettes to indicate to the reader to turn the page. This was commonly used with juvenile works.
I suggest having a simple method to have the codes and the accompanying definitions/elements appear. In some automation system, a simple click(s) on the field tag immediately causes a pop-up window to appear displaying the codes and explanations.
