Jeff Willis and Everyone: I admire Jeff’s dedication to cataloging the “watched vs. unwatched” with an Excel spreadsheet. I know I'd have difficulty keeping it current. As I might have 2 dozen or more sets at various states of completion at any given time, I opt for a much more low-tech solution. I simply take a 2” by 1.5” Yellow Post-It Pad and affix it onto the box, case, or package at the point (episode, selection, etc.) in the content listing that I am up to. This works for almost everything from the pages of Walt Disney Treasures booklets, to the backs of FOX plastic cases, to the interiors of WHV cardboard packages. This works for almost everything, except an atrocious package like that of CBS Paramount’s THE INVADERS, where, the fifth disc COVERS UP the content notes for the fourth and fifth disc! Don’t cha think they could at least allow us to read all of the content notes, without removing a disc? Don’t cha think?
