.Dear Members: I'm certainly no legal expert on copyright law, but my understanding is that any work original to you, whether written, pictoral, artistic, or in electronic format, is copyright to you, and users must obtain permission. This is partly obviated by the fact that PBS has been declared a public forum, and searchable by the public. It is further confused by the fact that email originated by you is copyright to you and should not be forwarded in its' entirety without permission, something that is frequently ignored. Thus, material you post on PBS may be quoted, but the email you sent is still copyright to you, even though it is the same material posted on PBS. Perhaps it would help to read some comments: http://whatiscopyright.org/ "Copyright laws grant the creator the exclusive right to reproduce, prepare derivative works, distribute, perform and display the work publicly. Exclusive means only the creator of such work, not anybody who has access to it and decides to grab it. " Top ten copyright myths explained http://www.templetons.com/brad/copymyths.html Copyright law does permit quoting, where such quoting is not the sole body of work of the person doing the quoting. In other words, Jane McGary's comments on western american lilies, and my comments in response, could be quoted if the person compared them, provided some additional comment(s) or comparison. (And acknowledged the original sources of the comments). Simply grabbing something you see and posting it yourself without adding to it is as much a form of theft as using someones' car without permission. Returning the car undamaged does not obviate the lack of permission. Modern computers have made it possible to access, and copy, many works which are copyright, as record companies have found. Technology almost always precedes the law, and this issue is still in transition. Is is also complicated by the fact that material can now be distributed worldwide, where laws vary widely on what is or isn't legally permissable. Again, I am not an expert, and doubtless have, and will, make mistakes in this area. What is right, and legal, and best for everyone, does change over time. I am interested in hearing what others feel is fair in this matter. I personally resent being used as an expert (ie, quoted), without my knowledge, as sometimes I make comments intended for one particular situation, which I know to be inadequate in other circumstances. Particularly with email, it is difficult to be both brief, and cover the subject properly. As an instance, there once was a question about apomixis in Lilium regale, and I responded with a couple paragraphs, despite knowing of several articles of many pages on the same subject. I provided what I felt was the answer the questioner needed, rather than all I knew, or knew of---and if someone had quoted me, I would have been embarrassed if a third party had asked me why I didn't include other facts that are fairly common knowledge.
