    The availability of different versions of the articles might lead to variations in quality, such as preprints or author manuscripts, which might not be peer-reviewed.
  • Dependency on Publisher Policies
    The availability of free articles depends heavily on individual publisher policies regarding open access, which can vary widely and affect what content is accessible.
  • Limited to Research Papers
    Unpaywall primarily focuses on research articles, so other types of academic content like book chapters or conference proceedings may not be available.
  • Requires Internet Connection
