Content coverage policy
The content that Scopus covers is driven by user demand. An independent Content Selection and Advisory Board comprising researchers and librarians reviews new sources for inclusion.

This helps to ensure relevant information is not omitted. All titles that conform to academic quality norms, specifically peer-review, and are published in a timely manner are accepted for consideration.

• Scopus covers titles from all geographical regions including non-English titles as long as English abstracts can be provided.
• To learn more about the content in Scopus including coverage, content processing, overlap with other databases, the Content Selection and Advisory Board and the pillars of Scopus content strategy, read the Scopus Content Coverage Guide and Julie Arnheim's Assessment of Scopus Content & Coverage.
• Suggestions for additional sources are welcomed. Simply complete this form to suggest a title for inclusion.
