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. Introduction The idea of GL is an emerging way of sharing information that is reputable and useful in various aspects of life. GL entails all information produced outside of the traditional publishing and distribution channels classical to the academic sphere. All information published or provided to the public but has not undergone peer review constitutes grey literature. For instance, all reports, policy literature, newsletters, government documents, written speeches and urban plans are produced and accepted as facts by all people. The same information can be used in research as indeed in different academic purposes. For instance, population statistics released periodically by governments of different countries are used mainly by researchers as sources of reputable information when undertaking any given research in different fields that requires the use of demographic figures. The impacts of GL in world science are gain traction since the majority of information provided by GL is usually useful in making policy and tends to be based on expert opinions informed by the academic and existing body of research. For many years GL was considered non-scientific due to the amorphous nature of the approach utilized by authors of reports.
