Searching English mathematics literature is an important part of academic research. Here are some common methods and techniques:

1. Use academic search engines, such as GoogleScholar, JSTOR, MathSciNet, etc. These platforms contain a large number of mathematical literature, and you can find related papers through keyword search.

2. Use online libraries: Many universities and research institutions have online libraries, such as Harvard University Library and Cambridge University Library. There are a large number of mathematical documents in the databases of these libraries, and you can find the papers you need by classified browsing or keyword search.

3. Use of professional journals: There are many professional journals in the field of mathematics, such as Journal of the American Mathematical Society and Mathematical Yearbook. The papers published in these journals are peer-reviewed and of high quality.

4. Use academic social networks, such as ResearchGate and Academia.edu. There are many scholars sharing their research results on these platforms. You can follow them or search keywords to find relevant papers.

5. Use of references: When reading a math paper, some references are usually listed. By consulting these references, you can find more related papers.

6. Use academic conferences: There are many academic conferences in the field of mathematics, such as the International Congress of Mathematicians and the annual meeting of the American Mathematical Society. The papers published at these conferences are the latest research results. You can find relevant papers by consulting the minutes of the meeting.

7. Use the advice of your tutor and peers: If you are conducting a research, you can ask your tutor or peers, and they may recommend some valuable mathematical literature to you.

The above are some common methods to find English mathematics literature, I hope it will help you.
