70's early '80's educational Series

I grew up in this time period and really enjoyed the programs that came on "educational TV". I've been trying to track down the following series: "The Community of Living Things" "The Human Community" "Eureka"-this is about physics, not the SciFi channel series "Gather 'Round"-Paul Lally telling story, Rae Owings drawing illustrations "Cover to Cover"- John Robbins telling the story and drawing illustrations"(there were a number of series in which he did this, also including "Read It") The Encyclopedia Britannica Series on the Human Body systems Call me a geek, or strange,or what have you, but I ended up being a teacher and these shows sparked the interest in learning and I never stopped. So if you have copies or know where I could aquire them I would appreciate the info. There are some educational tv stations around the country that still show some of these, but I can't pick up their stations to record the shows. So I'm hoping there are others out there like me....although I know that's asking a lot. Thanks
