GL plays a significant role in shaping research studies and academic endeavors, particularly in analyzing crucial outcomes related to contemporary issues. Its application is especially prevalent in the social sciences, particularly in policy-making, where it is essential to consider existing policies, their outcomes, and expert recommendations. The success of these outcomes is paramount in achieving optimal results and informing policy development in decision-making processes. The utilization of GL is increasingly gaining recognition across various areas of academia, demonstrating its notable impact. Grey literature's influence is evident in its application across diverse academic spheres. When conducting research, the primary objective is to utilize the most up-to-date information that supports the argument for fundamental research. The advancement of literacy, predominantly in education, enables individuals to engage with written materials, resulting in the emergence of GL across various mediums, including newspapers and pamphlets. These sources provide insights into different aspects of the relevant discipline. For example, government publications on news and policies, such as the impact of war on the economy, have become integral to academia and general knowledge accessible to the public today. The Vietnam War gave rise to numerous issues that significantly influenced societal perspectives. This period saw the emergence of new trends, including the formation of associations, the expansion of peace treaties between nations, and the establishment of agreements that facilitated more effective problem-solving approaches. Information disseminated by organizations and documented in peace contracts played a crucial role in shaping people's understanding and contributing to the development of robust outcomes.
