Since so many of the original entries from the SB list were undated, in the automatic creation process I attributed 30th July 1991 to them ā my birthday.
I have now found evidence of some being logged before that date.
The entry for the 6th May indicates I was typing up the list after a long weekend cycling around the Isle of Wight.
In the website, the entries are Sorted By the date they were created, newest first. Sampled Bigrams are given the same date as the Source Bigram.
