Thanks, sstvideo. I get complaints emailed to me every week that my Web site doesn't have enough photos or MP3s or video clips, and that all the text is just boring.
However, I feel very strongly about copyright law. I understand that other people disagree, or interpret the laws differently, and what they post to their sites is not my concern.
Personally, I tend to feel more forgiving about reproducing materials that are available for purchase, like on SesameSeventies.com. If there's no way that I can buy a copy of these materials, if the copyright owner refuses to provide a way I can see/hear them, and will not grant permission for re-use ... I think this is not on the same level as making illegal copies of music/video sources that are available for sale.
