History, as a discipline, relies heavily on the availability of primary and secondary sources. Researchers, students, and scholars require access to a wide range of materials to construct and analyze historical narratives. However, the cost of purchasing books and other resources can often be a significant barrier, particularly for those in developing countries or with limited financial means. The provision of free PDF books by UNED has helped bridge this gap, democratizing access to historical knowledge.
