Sources and Creative Commons licenses

99archive collects book files from different websites on the internet where the files are offered under Creative Commons licenses. The license, version, source, and attribution details can vary from one work to another. A Creative Commons label does not mean that every file has the same permissions: all six main CC licenses require attribution, while some restrict commercial use or adaptations, or require adaptations to be shared under the same terms.

Check the source and exact license for the particular work before reusing, adapting, or redistributing it. The license from the original creator governs the permissions for that work. If the license or source information on a listing is missing, unclear, or appears incorrect, send us the book title and page URL.
