For many treasures engaged in scientific research, ** is an important means to test research results.
When the ** is published, it will generally be used for scientific research, job hunting, promotion, etc.
However, it is generally one of the basic materials, and when using it as a performance of scientific research materials, it is necessary to issue a relevant inclusion certificate.
The inclusion certificate needs to be issued by the relevant search agency, and the issuance of the inclusion certificate is time-limited. Different databases issue certificates for different times.
Therefore, I will share the validity period of the database inclusion certificate from the following common databases and recommend a platform that I commonly use.
1.Validity period of the inclusion certificate?
2.Include citation agency recommendations.
1. Validity period of the inclusion certificate.
I have compiled the main ** databases currently on the market, and I will share the validity period of the proof of the important databases.
1) Foreign language databases.
1.The validity period of the SCISCI inclusion certificate is generally about six months.
SCI database is a sub-database of Web of Science, which is the world's most authoritative natural science citation database. Launched by the Institute for Scientific Information in 1960, it is the most authoritative journal literature search tool in the world.
2.ssci
The validity period of the SSCI inclusion certificate is generally about three months.
Three months can be regarded as the retention period, and the **file will not be deleted, and it can be re-printed when printing**).
SSCI is a cross-academic academic citation index, developed by the Institute for Scientific Information, which provides access to the current top research results in the field of social sciences through this database, which is currently available through Web of Science paid search.
3.The EIEI inclusion certificate is generally valid for about two years.
EI stands for Engineering Index and was founded in 1884 by the American Engineering Information Corporation. It is a comprehensive search tool for engineering and technology. It basically collects the world's top engineering and technical literature, covering all engineering fields.
4.inspec
The validity period of the inspec inclusion certificate is generally about six months.
Created by the IET R&D team, Inspec's database mainly serves global institutional analysis, popular subject analysis, cutting-edge scientific and technological term analysis, citation data analysis, etc., covering mathematics, physics, materials, software engineering, aerospace and other fields. Moreover, all the data in the database is manually added by data experts, which is very accurate.
2) Chinese database.
1.cssci
The validity period of the CSSCI inclusion certificate is generally two years.
CSSCI is the "Chinese Social Sciences Citation Index", also known as the core of Nanjing University, is a Chinese core academic database organized and evaluated by the China Science and Society Research Evaluation Center of Nanjing University, mainly used to prove the inclusion and citation of ** in the field of Chinese social sciences.
2.cnki
There is no specific time for the validity period of the CNKI inclusion certificate, which is roughly 6 months to 4 years.
CNKI, also known as "CNKI", is an academic resource library jointly initiated by Tsinghua University and Tsinghua Tongfang, including journals, masters, doctors**, conferences**, books, patents and other resources, which can meet the needs of various scientific research, decision-making applications, etc.
3.cscd
The CSCD inclusion certificate is generally valid for two years.
Founded in 1989, CSCD is the most authoritative retrieval tool in China in terms of natural science data, and has outstanding advantages in the development of interdisciplinary and new disciplines.
4.Wanfang. Wanfang database will keep the test report for 30 days, and the report can be kept forever after this period. (generally 5-10 years).
Wanfang is a large-scale domestic literature database founded by Wanfang Data Company, which basically includes all provincial journals in China, covering science, engineering, agriculture, medicine, and humanities, and is the most important tool for understanding domestic academic trends.
5.VIP. The VIP database will keep the test report for 15 days, during which time** the report can be kept forever. (generally 5-10 years).
The VIP journal database is developed by Chongqing VIP Information***, which is the largest digital journal database in China under the Southwest Information Center of Science, covering agriculture, medicine, economy, library and information, natural science and other fields, mainly providing digital processing of academic resources, data service solutions and other services.
The above is basically the most important database at home and abroad and the validity period of its inclusion certificate.
2. The institution that issued the certificate of inclusion.
The inclusion certificate needs to be issued by an institution with search qualifications. There are many institutions in China that can issue inclusion certificates, and as far as my personal experience is concerned, I especially recommend:
Zhangqiao scientific research ** inclusion certificate:
To stand out from domestic search agencies, I believe the platform has the following significant advantages.
1.Inclusion proves authority.
Zhangqiao Scientific Research is the only authorized unit officially designated!
Zhangqiao scientific research platform retrieval is supported by the Southwest Information Center of the Ministry of Science and Technology for the platform, and is a national first-class retrieval agency. I have been engaged in the work of inclusion and citation for 8 years. For those who want to issue a search certificate, the authority of Zhangqiao's scientific research inclusion and citation platform is very trustworthy.
2.The certificate is issued quickly.
For me, I personally think that the most prominent advantage of Zhangqiao Scientific Research ** Inclusion Certificate is that the citation certificate report is issued quite quickly, which is very useful for many small partners who urgently need the platform inclusion certificate. Generally, the relevant certificate can be issued within 24 hours on working days.
3.Fees are open and transparent.
The following are the relevant fees and charges of the Zhangqiao Scientific Research Inclusion and Citation Platform:
From the above figure, we can see that the platform's fees are very clear and reasonable, and there will be no other redundant charges. This is one of the reasons why I think the platform is very good.
By the way, the platform can also support invoicing!If you have a small partner, you can ask customer service about the situation.
