Public domain content refers to material that is no longer protected by copyright, meaning that it can be used freely by anyone without the need for permission or payment. This includes works whose copyright has expired, works created by the federal government, or those explicitly placed in the public domain by the creator. As a result, public domain content can be reproduced, distributed, and adapted without legal restrictions, allowing for greater access and usage in various projects. This distinguishes it significantly from content that is still under copyright, which may have restrictions or require licenses for use.
