Springer Nature Abstracting & Indexing Service

Springer Nature works with just about every Abstracting & Indexing  service, over 400 in total, through a dedicated A&I Department, and in close cooperation with our publishing editors.

Discovery Services provide a single search platform across their internal centralized index, allowing their subscribers to search across multiple databases to discovery content easily. Abstracting and Indexing Services are usually more subject oriented, but they are similar to the Discovery Services in that they also provide search capabilities to their users. The abstracting and indexing process, content selection and acceptance processes vary from publisher to publisher. Some publishers follow the indexing procedure based on reviewing the metadata, including abstracts, and basic bibliographic information. Other publishers may review full-text materials to index content. Abstracting and Indexing Services such as Web of Science and PubMed are curated by human indexers, whereas Google Scholar does not utilize human indexers.
