Sources of photos, sound recordings and videos that to the best of our knowledge may be reused without payment to a copyright holder in many circumstances. Verify the status of specific works. Keep in mind: giving credit to the original creator is sometimes necessary, and is always a good idea.
This is a sampler of resources and not intended to be comprehensive. Suggestions will not be accepted for sites that do not principally feature Alaska themed audio or images OR which are not either public domain or royalty free. If you are not familiar with these terms, read the information box towards the bottom of this page.
The two types of materials you will find on this page are public domain materials and royalty-free materials:
Public Domain - Public Domain materials have no copyright. They might be public domain because their copyright has expired (most pre-1927 materials) or because they are statutorily exempted from copyright, like most, but not all material produced by federal agencies.
Some post-1923 creators have explicitly dedicated their works to the public domain, waiving their rights under copyright law. An example of this can be found at the video The Access to Knowledge Treaty: What if WIPO Actually Worked For Us? A Digital Dialog Lecture with Cory Doctorow. You may do whatever you please with public domain materials and you do not have to pay for the usage of the work. Additional information about when an item becomes public domain can be found at Copyright at Cornell Libraries: Copyright Term and the Public Domain.
You can find out the most recent additions to the Public Domain by visiting the Public Domain Day page maintained by Duke University.
One popular family of licenses for royalty free works is Creative Commons CC. There are several types of CC licenses – some allow you to use the work in any way as long as you give attribution to the creator. Others will only allow you to use the work “as is” with no alterations. Yet other licenses grant different rights depending on whether your work product is a commercial use (i.e. whether it is given away or sold). Please review a work’s CC license before using it.
