Typically, registration of copyright in the United States requires a single application (and application fee) for each work in which copyright registration is applied for. For online works like social media posts, the cost (in both effort and fees) to file a separate application for each post can often outweigh the benefits of registration. In part to address this issue, the U.S. Copyright Office has launched a new process for Group Registration of  Short Online Literary Works. As the title suggests, the process allows a creator to register copyright in multiple (up to 50) online literary works at a time, with a single application and application fee. For more information, including further requirements, see the U.S. Copyright Office Circular 67 here.
