Considerations
There are several considerations you need to account for before signing a publishing agreement. Be sure to investigate publisher agreements for their copyright guidelines once you have decided on your needs as an author. Carefully read through and analyze the publishing agreement. You may be in agreement with their policy, or you may need to further negotiate your copyright requirements.
Do Your Research
Start with an initial search through the SHERPA/RoMEO database to begin your research on the publishing agreement. This free database contains the copyright and self-archiving policies of more than 22,000 journals and periodicals. Do note that policies are updated periodically and the database should not be the authority when ultimately determining publisher terms and conditions.
Verify the Publisher
Next, verify and research the publisher website for author rights. Discover as much as you can before entering into a contract. Sometimes journals publish this information on their websites, but it may be necessary to contact the journal's editors directly to request it.
