Is Packaging for the medium or the release.
Examples of same medium packaging within the “box” .
Example1, Original Album Classics, Original Album Series, etc.
A cardboard box containing 5 CDs each in its own cardboard sleeve, barcode on the box only.
Example2, The Turtles - The Complete Original Album Collection
A cardboard box containing 5 CDs each in its own cardboard sleeve, barcode on box and different barcode on each sleeve (In this case the individual CD sleeve releases took over a year to be released).
Example3: Crossroads, Bear Family Jerry Lee Lewis, and others.
A cardboard box containing 3+ CD jewel cases, Barcode on the box only.
Example3: Some TimeLife series, Some jazz and blues, and others.
A cardboard box containing 3+ CD jewel cases, Barcode on box and different barcode on each jewel case.
Then there is:
The Beach Boys Pet Sessions,
A cardboard box containing 3 jewel cases, 1 cardboard sleeve, and a book.
Grateful Dead - So Many Roads (1965-1995)
A bound book of cardboard sleeves slid inside a cardboard box case.
I suspect “Other” for all but the Grateful Dead - So Many Roads, but I think there is a case to be made for cardboard sleeve and jewel case on some of the others to show how the medium is packaged.
