Google Scholar Content Clustered Together

Google Scholar indexes content from multiple sources and frequently identifies more than one version of the same article. To avoid duplicating entries, the Google Scholar algorithm automatically clusters articles that share similar metadata (such as title, authors, and publication year).

To view all available versions of a given article, click the “All X Versions” link located at the bottom right of each search result.

Occasionally, an article may be indexed as a “version” of another article. This typically occurs when two articles have similar metadata, making it difficult for the algorithm to distinguish between distinct publications and different versions of the same work. In other cases, clustering may occur due to an error within the Google Scholar algorithm.

If you encounter such an issue, please notify indexing@springernature.com so that it can be reviewed further.
