Jan, I have both of these DVDs. They are very different.
The glossary includes an interview between Meg and Elizabeth which is pleasant to watch. They are ensconced in Elizabeth's house wearing cozy knitted shawl (M) and sweater (E) and from time to time they cut to the outdoors, where snow is falling in the Wisconsin woods. Mikey the cat is also there. The rest of the video consists of short clips of techniques demonstrated. The menu of items in the glossary includes a lot of stuff, but not everything in knitting. Sometimes E. demonstrates, sometimes M. There is stuff from when M. was a young woman but later, I presume after E.'s death, additional demonstrations by M. were added. I learned a lot from this video.
The workshop is the TV show that was on public television. Family members are off screen to pass things to E. as she teaches/demonstrates making particular items.
I used to go to sleep watching the glossary every night! I think I may have picked up a few things up in my sleep.
