1. Library query: The library is the main way to obtain documents, which can be searched through the library's catalog system and electronic resource library. In addition, the library also provides professional librarians to help users with literature retrieval and data collation.
2. Academic search engines: academic search engines, such as GoogleScholar, WebofScience, CNKI, etc. , you can easily retrieve various academic journals, conference papers, dissertations, etc. These search engines usually provide advanced retrieval functions, which can be filtered according to keywords, authors, publication years and other conditions.
3. Specialized databases: Specialized databases of specific disciplines, such as PubMed (medicine) and IEEEXplore (engineering), provide a large number of high-quality academic resources. These databases usually require a paid subscription, but many university libraries will provide free access.
4. Preprints and open access resources: Preprints are academic papers that have not been peer-reviewed, and can be found on platforms such as arXiv and bioRxiv. Open access resources refer to academic resources that provide free full-text downloads, such as PLOSONE and ScienceDirect. These resources can help users get the latest research results quickly.
5. Reference tracking: When reading a document, you can find more relevant research materials by looking at its reference list. This method can help users find some unknown research results and broaden their research horizons.
6. Expert consultation: Ask experts in related fields to know the research materials and documents recommended by them. This method can help users find some authoritative research results and improve the quality of research.
7. Social networking: Use social networking platforms such as LinkedIn and ResearchGate to pay attention to researchers and institutions in related fields and obtain their research results and trends. This method can help users keep abreast of the latest progress in the research field.
