10 Public Domain Guidelines
Public Domain Guidelines |
1. Give credit where credit is due.
Whenever a public domain work is used, the author(s) (if known) should be cited. Citation may be made in accordance with any relevant scientific, scholarly, disciplinary or community practice. Additionally, if a public domain work has been curated or made available by a person other than the author, that provider should also be appropriately credited.
2. Provide original source information.
When redistributing all or part of a public domain work in modified or unmodified form, its source (“provenance”) should be identified in accordance with any recognized standards in the applicable field or community, or by the means recommended by the provider. This usually includes providing a link back to the website page (if any) where the work was originally discovered, and making the link reasonably prominent and accessible to users. If the work has been curated and the curator has associated identifying information with the work, such as catalogue data or information about its inclusion in a collection, then provenance information should include that associated identification.
3. Show respect for the original work.
When a public domain work is modified and redistributed, any modifications made to the original should be clearly identified and the modified work should be labeled as having been modified, so that users are not confused as to the source of modifications. If the provider of a public domain work has requested that no modifications be made, or that the work be used consistent with identified quality control requirements, then users should consider observing the request.
4. Preserve public domain marks and notices.
Users of a public domain work should not remove any public domain mark or notice that has been applied, or provide misleading information about its copyright status.
5. Protect the reputation of authors and providers.
Whenever a public domain work is used or modified, the use or modification should not be attributed to the author or the provider of the work. The trademarks, name, or logos of the author or provider should not be used to endorse (or imply origin of) the public domain work without consent.
6. Contribute discoveries back.
Users of a public domain work who generate new discoveries or works, or who add value to a public domain work, should release the discoveries, modifications or additions into the public domain through CC0 or an equivalent tool.
7. Share knowledge.
When the user of a public domain work has additional information about the work (such as details about its provenance, author, content or other possible rights holders), the user should share that knowledge. This may include tagging, annotating or commenting on a public domain work that is published online.
8. Maximize a work’s potential.
When a public domain work exists in multiple formats or media, it should be made available in the preferred format for maximizing accessibility, use and modification.
9. Support efforts to enrich the public domain.
Users of public domain works should support the efforts of the work’s provider to preserve, care for, digitize and/or make available public domain works. This support should include monetary contributions, particularly when the work is being used for commercial or other for-profit purposes and the provider is a public or non profit institution.
