摘要：
Some implementations include searching for and analyzing public-domain-status information about works (such as e-books) over the Internet. A computer system may search for works recently made available online that are categorized as being in the public domain. Associated metadata is analyzed to generate a confidence level regarding whether the works are in the public domain or protected by copyright. Based on the confidence level, decisions can be made, such as whether to make the works available for free in a particular country.
