The library is the best place to find documents. You can find relevant books and periodicals in schools, public libraries and professional libraries. Databases such as China HowNet and Wan Fang Data also provide reading and downloading services for many original documents.
2. Use electronic resources
In addition to the traditional printed documents, most of the original documents have been converted into electronic documents and recorded in various databases, such as Google Academic, PubMed, ScienceDirect and so on. Using these electronic resources, we can quickly find relevant documents.
Use the link provided by the author
Some authors will provide links or citation sources of relevant original documents in their articles, and we can find relevant original documents through these links or citation sources. If the author does not provide relevant links or references, we can also obtain them by sending an email to the author.
Step 4 use citation index
When we find a useful reference, we can use the citation index to find the original document of the document. Citation index refers to the list of references contained in the literature, which can help us find the cited original literature.
5. Use network resources
In addition to using database and library resources, we can also use some informal network resources to find original documents. For example, find useful research in academic forums and find relevant papers with the help of academic social networks.
In a word, searching for the original literature in the reference literature requires us to search and utilize various resources in multiple channels and directions, find the most suitable search method through continuous trial and exploration, and accumulate our own literature retrieval experience.
