One good way to obtain these rights is to add an addendum to the agreement you sign setting out terms that are important to you. The University of Michigan has prepared an addendum to meet the needs of U-M faculty and students. To use it, simply:
Download the U-M author's addendum
Attach the addendum to the agreement sent by the publisher, sign, and return it along with the original agreement.
Make a copy for your records.
Include a note or cover letter alerting the publisher that it's there.
If you are lucky, the publisher will accept it without objection or with minor adjustments. However, if the publisher insists that no changes can be made to the original agreement, it is up to you to decide whether you still wish to publish with that journal, even if you can't keep all of the rights you want.
