Yeah, this is the pattern I have been taught. Label the Front of the separate Releases. And the Back of those Releases.
In my early days I made a few mistakes thinking the booklets had backs too, but they don’t. Just page numbers to add to the Comment field.
But you are only doing small boxes…

Only the 238 images uploaded by tigerman325 there… epic work…
Every Release is in a little Gatefold sleeve, with one or two CDs in there, and a little booklet. For each release. I have a Chinese knock-off of this and was sooooo glad to see that tigerman325 had already done the heavy lifting. I could then just add the oddities from my box.
I am rather glad the Ozrics box I did last week didn’t have any booklets in it.
