SCI retrieval number: the commonly used code for SCI retrieval number is WOS login number or IDS number. You can find these two numbers at the bottom of the paper details page after searching for a specific paper from the Science Web. Usually, the format of WOS registration number is A 1970H022600020, and the format of IDS number is H0226.
Extended data:
The paper retrieval number is relative to the document retrieval platform, which is generally considered as "retrieval number". Being included is relative to the literature database, and they are not in the same dimension.
Specifically, SCI corresponds to SCIE (Science Citation Index Expand) abstract database, ISTP corresponds to CPCI-S abstract database, and EI corresponds to Ei Compendex abstract database. These abstract databases belong to a retrieval platform and must have corresponding retrieval numbers.
Judging from the retrieval numbers of SCI and ISTP, the new version of * * * is identified as WOS and cannot be distinguished. Therefore, at present, these retrieval numbers do not have the function of representing specific databases. Then, the retrieval number cannot be a sufficient condition for articles to be included by SCI, ISTP and EI, but only a necessary condition.
