Thanks for the compliment, Thijs. To answer your questions.
1 No, this listing isn't just for the puppet characters associated with all of these wonderful Henson productions. For the human characters, yes the living, this list is meant too. So when they get to my door, tell them Boris sent you! The list's rully meant to compile all the characters that have appeared on the shows throughout the years, and that includes human characters but not celebrities nor guest stars of TMS if that's what you're thinking that this list could be expanded to. Originally, my intent was to get just the three main branches, Sesame Street, The Muppet Show and Fraggle Rock; but after all the vonderful help from fellow forum members and other websites, I decided to expand it to the movies and TV specials for those three branches and The Jim Henson Hour and Muppets Tonight since the two of those could be considered as new versions of The Muppet Show.
Currently considering if it should be extended to other licenses as Luke suggested, but I'd like to see what others think before making a decision. And those who are interested can make the case either for or against stuff like Bear in the Big Blue House, World of Dr. Seuss, Muppatops, and the like.
2 Yes, at some point I'd like to get this list on the internet hosted at some site of my own. The list is just phase 1 of my master plan. Right now, that's all I can do since I'm studying for a law degree. But once that's finished and I've taken a course in independent living, then the real work will begin. The rest of the project entails actually getting funded sponsorship (probably through the National Federation for the Blind) and going to Henson HQ to do real research. Get photos of the characters to go with the listing, textual verbal descriptions of the characters, go over all the episodes from the productions with an assistant of my own and one of theirs to ask if each new character seen would count as a Henson production character as denoted in my master listing, get episodes reviewed, take down notes for the shows and songs and sketches and episode numbers/airdates, etc. All in hopes of producing a triple threat: printed version as a definitive textbook/encyclopedia of the entire Muppet Universe, audio cassette version of the print version for my fellow visually-impaired community members, and a massive website hosting all the information gathered as mentioned above yet not limited to just that which has already been mentioned.
Hope this helps and have a good day.
