* Anonymous works: These are intentionally published without the author's name. This could be for various reasons, including maintaining anonymity for safety, to focus on the content itself rather than the author's reputation, or due to authorship being unclear (like folklore passed down through generations).
* Works with ghostwriters: The actual writer remains unknown to the public; only the credited author (often a public figure or celebrity) receives the credit.
* Corporate authorship: A work produced by a company or organization, where individual contributors aren't specifically named. This is common for reports, white papers, or marketing materials.
* Folklore and traditional tales: These stories often have unknown origins and are passed down through oral tradition, with no single author or original writer.
* Works with lost or unknown authors: An older text might exist without clear attribution due to damaged or lost documentation about its origin.
* Content created collaboratively where individual contributions are not tracked: This often occurs with online content like wikis where many people edit and add to a single page.
* Works using pseudonyms: While an author is technically present, they use a pen name and their real identity is not publicly linked to the work. This is different from *uncredited*, but if the pseudonym is unknown, the work is effectively unattributed.
Essentially, anything published without a clearly identified and acknowledged creator can be considered an uncredited author or publication.
