The significance of literature:
Literature refers to all kinds of materials that have been sorted, classified, catalogued, indexed and kept in libraries, archives, museums and other information institutions, including books, periodicals, newspapers, dissertations, research reports, patents, standards, works of art, audio-visual products, electronic documents and other forms of materials. Literature records the knowledge and achievements of human society in culture, history, politics, science and art, and is an indispensable source of information for academic research.
In academic research, it is very important to find documents, because documents provide reliable support and basis for research. By searching the literature, researchers can understand the previous research results, theoretical framework and methods, and provide reference and inspiration for their own research. At the same time, literature retrieval can also help researchers to supplement their knowledge, broaden their horizons and better understand the current situation and trends of academic research.
Original documents: also known as first-hand documents, refer to the original materials that record a phenomenon, idea or event at the earliest, usually including documents, materials, field notes, medical history, cultural relics, physical objects, etc. , such as history books, documents, experimental data, etc.
