If you determine that the work you want to use is protected by copyright and that your use is not a fair use and no other exceptions apply, you must obtain permission from the copyright owner. Examining a copy of the work and its copyright notice (©) will help you identify the copyright owner whether it be the author(s) or publisher. Remember that the absence of a copyright notice does not mean the work is in the public domain.
Contact information for authors and publisher websites can be located by searching the internet. Publishers' websites often have a section called Rights or Permissions that spell out their preferred method for requesting permission to reuse their content.
When contacting the copyright owner, clearly explain your intended use including a complete citation for the work, the number of copies to be made, and the exact nature and purpose of the intended use.
The process of obtaining permissions can be streamlined by using the Copyright Clearance Center (CCC) to get permissions or license content. CCC offers pay-for-use services for academic faculty and staff. CCC's fee for the services will be added to the royalty fee charged by the copyright owner. Many publishers also direct requests for permissions to CCC's RightsLinks service.
