The production team also used the "Encyclopedia Fragglia" title for an internal document compiled by Karen Prell and other production staff. The document listed production data for each episode, including air dates, tape dates, song titles, performer roles, and director and writer credits. The document has never been available to the general public; it is simply a photocopied set of pages printed on a dot-matrix printer.
In an interview, Prell explained her process and motivation:
In the late '90s, Jerry Juhl gave copies of the document to two fans who were working on Muppet projects -- Danny Horn, who was publishing MuppetZine at the time, and Chris Vaughn, who created Chris' Fraggle Rock Page.
This document has proved to be an invaluable resource for Fraggle fans, providing official character names, song titles, tape dates and performer roles.
