1. Academic databases: such as JSTOR, PubMed, ScienceDirect, Springer, etc. These databases contain a large number of academic papers and periodicals, and you can find relevant references through keyword search.
2.GoogleScholar: This is a free academic search engine, which can search various academic resources, including papers, books and dissertations.
3. Library: University libraries usually subscribe to a large number of academic journals and databases, and can search for relevant documents in the library's electronic resource system.
4. Academic conferences: Attending academic conferences is a good way to obtain the latest research results, and conference papers are usually included in conference proceedings, which is an important source to find references.
5. Expert recommendation: If you have specific experts in your research topic, you can try to contact them to see if they have any recommended references.
6. Citation tracking: When reading a paper, you can check its list of references, and you may find other related studies. At the same time, you can also use citation management tools (such as EndNote, Mendeley, etc. ) to manage and track your references.
7. Social media and academic communities: such as ResearchGate and Academia.edu, where researchers will share their research results and reference materials.
8. Pre-printed servers: such as arXiv, bioRxiv, etc. These servers will publish the latest preprinted scientific papers, sometimes even earlier than the official publications.
The above are some common ways to find references for papers, and I hope they will help you.
