Each disc begins with a TV Montage introduced by Alisa and featuring one clip from each of the 4 seasons (all of which are presented within the main program). Each period begins with a look through a scrapbook representing the time periods, and many clips begin with behind-the-scenes photos related to the clip (with the first few seconds of audio heard over the picture). The set also comes with a commemorative booklet, a shortened 24-page version of the BYG Dictionary . Early copies were hardcover, but when distribution switched from Family Home Entertainment to Disney the booklet was changed to paperback.
