MIT Copyright Amendment Form
Since I teach a session for scholarly authors regarding negotiating copyright with publishers, I find and collect forms such as these.
I like this MIT one for its brief instructions on the first page, helping authors just that much more.
I especially appreciate this clause:
a. The Author shall, without limitation, have the non-exclusive right to use, reproduce, distribute, create derivative works including update, perform, and display publicly, the Article in electronic, digital or print form in connection with the Author’s teaching, conference presentations, lectures, other scholarly works, and for all of Author’s academic and professional activities.
because scholarly authors seldom realize they are giving away these rights when they sign fully copyright over to the publisher.
