Some authors will put the full text of their published papers on their personal homepage or laboratory homepage, and you can also have a look.
Step 2 ask the author for help
Contact the correspondent or the first author of the article directly by email. Generally, they are willing to share their articles with you and increase their citation rate. If the big boss is busy, he can find his students.
Ask a friend for help
Ask for help from classmates or good friends of key universities. Generally, their libraries will buy a lot of full-text databases, but this method can't be used often, for fear of disgust.
4. Internet search
Find links through search engines such as Google and Baidu. Some websites hang the full text of relevant valuable documents and download them directly, but it takes you a lot of precious time, just like "looking for a needle in a haystack".
5. Paper copy
Go to the school library to find paper-based Chinese and foreign periodicals, and then copy them. If literature is an unknown magazine in a small country, it is difficult to find it.
Of course, if you want to know more about SCI papers, you can find international science editors, who provide many links and introductions to SCI papers. They have abundant cooperation resources for paper publishing, which can meet the needs of customers in various industries, including Peking University core publications, core publications of scientific and technological statistics sources, SCI publications, EI publications, CSSCI publications, and national and provincial key general publications.
