The S2CID (Scopus to CrossRef Identifier) is a unique identifier used to track and manage academic papers within the Scopus database, a comprehensive abstract and citation database of peer-reviewed literature. The S2CID is part of the DOI system and is used to facilitate the linking of articles across different databases and platforms.

Overview

The S2CID was introduced by Elsevier, the company that manages the Scopus database, to provide a unique and persistent identifier for each article indexed in Scopus. This identifier is used to ensure that articles can be easily found, cited, and linked across various academic and research platforms.

The S2CID is similar in purpose to other identifiers such as the DOI and the PMID, but it is specifically tailored for use within the Scopus ecosystem. It helps in maintaining the integrity of citations and references by providing a stable link to the article's metadata and abstract.

Structure

The S2CID is a numeric identifier that does not have a fixed length. It is assigned sequentially to articles as they are indexed in Scopus. Unlike the DOI, which can include alphanumeric characters and is structured to include a prefix and suffix, the S2CID is purely numeric.

Usage

The S2CID is primarily used by researchers, librarians, and academic institutions to:

• Track citations and references of articles within the Scopus database.
• Facilitate the integration of Scopus data with other bibliographic databases and reference management tools.
• Ensure accurate and consistent citation of articles in academic publications.

Comparison with Other Identifiers

While the S2CID is specific to Scopus, it complements other identifiers such as the DOI and PMID. Each of these identifiers serves a unique purpose and is used in different contexts:

• The DOI is a widely used identifier for digital objects, including journal articles, books, and datasets. It is managed by the International DOI Foundation.
• The PMID is used to identify articles in the PubMed database, which focuses on biomedical literature.
