The first video is the same as https://softwarepreservation.computerhistory.org/FP/#Backus1... .
I hadn't seen the Group Meeting video; I will add it (even though it's very rough).
I will change the entry for [Booch2007] to include the video as well as the transcript.

In that first diagram (https://softwarepreservation.computerhistory.org/FP/Composin...), A and B are supposed to be pure functional programs; side-effects are modeled by each one outputting a new version of each modified input. In the second diagram (https://softwarepreservation.computerhistory.org/FP/Strict_H...), as actually implemented in FL, they stick to strictly leftmost-innermost evaluation order so that side-effects are at consistent (but this presumably prevents parallel evaluation).

Can we move this conversation to email? I am not sure what diagrams you are referring to.

Thanks very much; I in turn will add a link the Related Resources section. If you'd like to be recognized as other than metazip then let me know via email.
