What public domain means
A work in the public domain is not protected by copyright in the relevant jurisdiction, or the applicable rights have expired or otherwise do not restrict the use in question. Copyright terms vary by country, and a recording can have rights separate from the underlying text.
The text and the recording are different layers
An old novel may be in the public domain while a modern commercial narration of that novel is still protected. Free audiobook projects typically use recordings that are themselves released under terms allowing public access, or recordings created from public-domain texts under a suitable legal framework.
Where people commonly find public-domain audio
Reputable sources include volunteer audiobook projects and digital archives that clearly state the rights or status of the files they provide. When in doubt, check the source page for the recording rather than assuming that an old title automatically makes every audio version free to redistribute.
Why region still matters
Copyright terms differ around the world. A catalog that serves multiple countries may need to filter or restrict titles based on the listener’s region. That is a normal part of responsible digital distribution.
What BookEar GO is building
The initial BookEar GO online catalog focuses on public-domain or otherwise authorized audiobook content. The aim is to make classic audiobooks easier to discover and listen to on Android and compatible Wear OS devices.
