I believe that friends are not unfamiliar with EI collection and EI retrieval of these two words, but there are also many friends of these two nouns are not very understanding of the resulting mix, so let's come together with Eskelan small make up to see the following introduction to EI collection and EI retrieval.

　　Ei retrieval and Ei collection means the same, but the statement is different. Retrieval and collection is the state after the publication of the paper, but also the final state after publication. Now many units, especially the evaluation units of the paper requirements not only see the journal, but also can be retrieved on the retrieval platform, and the requirement to provide retrieval evidence to be effective papers.

　　I. EI retrieval certificate issuing method

　　1. Search by yourself: SELECT Compendex from the drop-down menu of SELECT DATABASE. The default DATABASE is Compendex. After retrieving the results, we need to check whether the paper information is the paper we retrieved, and then directly go to the university with qualification to issue the retrieval certificate to get it.

　　2. It can be sent to colleges and universities that are qualified to issue EI retrieval certificates by email. The content of the email should be explained as follows:

　　(1) Retrieve paper title and paper number (paper title repetition rate is relatively high, and paper number is the only way to ensure the accuracy of retrieval proof);

　　(2) Search databases, such as EI

　　(3) open alone or several articles open together;

　　(4) to JCR division or CAS division;

　　(5) to several copies of the search proof;

　　(6) to partition or impact factor and partition;

　　(7) whether the impact factor and zoning are current or up-to-date;

　　The university will track whether the paper has been retrieved after receiving the email of issuing the search certificate. Once the paper has been retrieved, it will issue the paper according to the author's email requirements, and send the author an email informing the place of collection.

　　2. How long will it take for EI papers to be retrieved after publication

　　Ei papers after see publication will not immediately on the retrieval platform to search, but need 1 to 2 months by the related personnel to upload paper information to retrieve platforms can be retrieved, so have a review of the job requirements or your unit or proof of paper retrieval is required for colleges and universities, it must be prepared ahead of time, leave enough paper retrieval time, avoid the paper failed to retrieved before use, Influence the use of papers.
