Abstracting & Indexing for Journal Authors

Abstracting and Indexing (A&I) services enable scholars to search and find journal articles and ebooks based on metadata tags and abstracts. Researchers rely on these services to quickly and conveniently find publications on relevant topics.

What is Abstracting & Indexing?


A&I services unlock the content of academic journals and ebooks using metadata and abstracts, thereby improving the ease of use of academic literature. The metadata used in abstracting & indexing services includes the title, author, publication date, journal title, volume and issue number, page numbers, subject area, keywords, DOI, and other key elements. Inputting search criteria brings up the metadata and abstracts of relevant articles, chapters, and books, along with links to the full-text versions.

If the user already has full-text access or if the relevant publications are available in open access formats on a journal platform, they will be able to access the full-text immediately. Otherwise, readers can be provided with information from the publisher or rights holder on how to access the publication.

At De Gruyter, our Abstracting & Indexing team is dedicated to achieving maximum exposure of your article in all of the relevant services, and to working with you to constantly improve your article’s rankings.

Other Collaboration Tools


Our website also uses a range of collaboration tools, all of which can help bolster citations:

  • Altmetrics Explorer: Delivers reports on how our articles are shared, especially on social media

  • FundRef: Identifies the funding body of the research

  • ORCID: Unique identifier for scientists

  • Portico: Perpetual archiving of all journal content on degruyter.com

The key component of our service is to provide each journal with a sophisticated electronic content hosting and distribution platform. The electronic version of the journal is provided with a sleek, professional and user-friendly interface thanks to the platform’s numerous functionalities, such as:

  • Automatic creation of active reference links

  • Automatic delivery of abstracts to abstracting databases

  • Easy integration with library systems and user authentication

  • The option to publish articles online as they are finalised (rather than having to wait for issue compilation)

The Journal Impact Factor (JIF) and other scientometric indicators


Clarivate Analytics’ Journal Impact Factor (JIF) is the most widely used scientometric/bibliometric indicator for journals. The JIF measures the average number of citations received by a journal’s articles published in the two preceding years. The higher the score, the more influential the journal. The score range, however, differs significantly from discipline to discipline. The results for the previous year are published in the Journal Citation Reports around the middle of each year.

CiteScore, SCImago Journal Rank, and Source Normalised Impact per Paper are three other scientometric journal indicators that are now well established. They are based on the Scopus database and publish the previous year’s results every summer:


  • CiteScore measures the average number of citations received by a journal’s articles. Unlike the Journal Impact Factor, however, it assesses citations over a four-year period, rather than a two-year period.

  • SCImago Journal Rank (SJR) not only considers the number of citations received by a journal’s articles but also the importance of the journals that cite them. The SJR scores are calculated using an algorithm based on Google PageRank.

  • Source Normalised Impact per Paper (SNIP) measures citations relative to the total number of citations in a given subject area. SNIP assesses the ratio between the average number of citations received by a journal’s articles and the citation potential in the relevant subject. This indicator makes it possible to compare journals across different subject areas directly.


You can find the scientometric scores for our journals on the relevant product pages of our website.
