Science Commons: Scholar's Copyright Addendum Engine
As I've been presenting sessions on author rights to scholarly authors, I have been gathering resources from here and there on the net. I was pleasantly surprised to see the launch announcement for this site as I was catching up with emails. It appears to manufacture an attractive addendum for the specific citation, which assures that the items is identified in the text of the addendum.
"The Scholar's Copyright Addendum Engine will help you generate a PDF form that you can attach to a journal publisher's copyright agreement to ensure that you retain certain rights."
The page also contains a link to the MIT author's addendum, another favorite of mine.
