I know not many remember, but there was a revival The Twilight Zone series that started in 1985. Originally it ran for an hour and each episode would have one, two or three stories in it, which allowed them to tell shorter or longer stories than the half hour format would.

(If you're not familiar with this series, read the Background section below for the details and the unusual situations involved that led to this question.)

I've been watching the syndicated version of this series recently on Chiller and found a list of all the episodes and stories for this version of The Twilight Zone. I've found six stories from the first season seem to be missing from the syndicated package:

• 
  Children's Zoo


• 
  Kentucky Rye


• 
  Still Life


• 
  Devil's Alphabet


• 
  The Library


• A Day in Beaumont

I haven't seen these stories in the syndicated package on Chiller and in the Wikipedia, there is no Syndication heading in the entries for these stories, as there are for all the other stories that I've seen in syndication.

Were these stories just left out of the syndication package? If so, was there a reason for that? (It'd be cheaper to include them and produce fewer half hour episodes to fill out the package, wouldn't it?) Is there any way to see these stories now (other than buying the DVD) or are they out of syndication forever?

If anyone has any information on these episodes, I'd like to hear about what happened.

Background:

CBS was so sure the series would be a hit and run for years that it pre-signed deals for syndication for 100 episodes even before the first season was done, but due to ratings, the series was cancelled after 11 episodes in the 2nd season. CBS hired a new production team and produced 30 episodes (these were one half hour each) so there would be enough episodes for syndication.

When they did that, they also took most of the stories from the one hour episodes and edited them. Some were combined into one 30 minute episode with two stories, others were given added footage to extend them to a half hour. Longer episodes were edited down to half an hour.

Don't know if you're a Netflix subscriber, but if you are, the series is available. All of the episodes you mention are available. http://movies.netflix.com/WiMovie/The_Twilight_Zone_Season_1_The_80s/70018590?trkid=2361637
If you're not a member, might be worth it to join for a month ($8) if you want to see the episodes badly enough.

I believe this was purely a business decision, as was the production of a third season (low-budget) to fill out this series for syndication.

Epi-log was a pre-Internet magazine devoted to episode guides. In #36, Nov. 1993, William E. Anchors, Jr. wrote of the editing down of the CBS episodes (which began as a one-hour show with multiple segments per hour) to a half-hour series for the syndication market:

This proved to be a major undertaking, as some stories needed to be
shortened, while others were actually made longer by adding in unshown
footage not aired during the CBS run.

I haven't done other research, but as a fan of the series don't recall any other reason. The series was a disappointment in the ratings, and the rights-holders made the conservative choice to return to the familiar Zone format of half-hour stories. It meant dropping some of the shorter segments rather than confuse casual viewers.
