The Another World Synopses Index is the best place to locate a specific date for which I have posted a synopsis so far.
So far I have posted the following ranges:
One block of snippets of Catlin & Sally's dialogue from mid to late August, 1984.
From the earliest preserved synopsis in early September 1984 to the end of December 1986.
From mid-June 1987 to the beginning of November 1987.
