Scopus developers claim to index over 14,000 STM (Science, Technology, and Medicine) and social science titles from 4,000 publishers, positioning it as a leading abstract and indexing database. It offers superior coverage of emerging markets, providing access to critical, high-quality research from developing countries often not found in other databases. Scopus also integrates automated and manually curated data to generate current author profiles, enhancing its utility for bibliometric analysis.

Scopus's Content and Features:

Coverage: Extensive coverage across science, technology, medicine, social sciences, arts, and humanities. It boasts 100% MEDLINE, EMBASE, and Compendex coverage in health sciences titles.
Citations: Contains over 1.4 billion citations, with indexed papers reportedly enjoying 10-15% more citations.
Metrics: Provides various journal-level metrics such as CiteScore (CS), SCImago Journal Rank (SJR), and Source Normalized Impact per Paper (SNIP), which are used for journal evaluation and ranking.
Curation: Curated by independent subject matter experts, ensuring a source-neutral and high-quality database.
Patent Information: Indexes patent databases from USPTO, EPO, JPO, WIPO, and UK Intellectual Property Office.
AI Integration: Elsevier launched Scopus AI in January 2024, a generative AI tool leveraging its vast curated scientific literature database to revolutionize research workflows.

Given its comprehensive coverage, particularly in STM fields and its strong global footprint, Scopus holds a substantial portion of the academic database market. Its integration with Elsevier's extensive publishing portfolio and its continuous innovation, such as Scopus AI, reinforce its market position.

Web of Science: Clarivate's Authoritative Research Platform

Web of Science (WoS), part of Clarivate Analytics, is arguably the world's oldest and most authoritative database of research publications and citations, originating from Eugene Garfield's Science Citation Index founded in 1964. It is a paid-access platform offering access to multiple databases that provide reference and citation data from academic journals, conference proceedings, and other documents across various disciplines.

This tutorial provides an excellent guide on how to leverage Web of Science for systematic literature reviews, a crucial aspect of academic research. It demonstrates the platform's advanced search capabilities, highlighting its importance in identifying relevant scholarly work and conducting thorough bibliometric analyses. Understanding these functionalities is key to appreciating Web of Science's market value and its continued relevance to researchers.

Web of Science emphasizes selectivity and quality, covering around 34,000 journals today. It provides tools for analyzing citations, identifying major authors in a field, and understanding the impact of research through metrics like Journal Impact Factor (JIF) and other citation analyses.

Web of Science's Strengths and Market Standing:

Legacy and Authority: As the pioneer in citation indexing, WoS has a long-standing reputation for quality and selective coverage.
Core Collection: Its Web of Science Core Collection is highly regarded for its rigorous selection process, focusing on high-quality academic journals.
Impact Metrics: Offers comprehensive tools like Journal Citation Reports (JCR) for transparent, publisher-neutral data and metrics, aiding in confident decision-making for researchers and institutions.
Multidisciplinary Coverage: Indexes scholarly literature in sciences, social sciences, arts, and humanities, including journals, conference proceedings, and books across over 250 research areas.
Emerging Content: Includes emerging research in preprints, dissertations, theses, and awarded grants to provide a wide view of the scholarly landscape.

While both Scopus and Web of Science are considered leading databases, they are not entirely inclusive and often complement each other. Historical comparisons show some overlap but also unique content. For instance, an overlap study noted that 7% of articles were shared between WoS and Scopus, while 93% were unique to one database or the other, reflecting their different indexation policies and content selection strategies. Web of Science's rigorous selection criteria and its deep historical data continue to make it a preferred choice for many researchers and institutions, contributing significantly to its market share.

Dimensions: The Holistic Research Discovery Platform

Dimensions, provided by Digital Science, differentiates itself by offering a more expansive view of the research landscape beyond just publications and citations. It is described as providing the world's largest collection of linked research data, accessible via its web platform and workflow-based applications. Dimensions integrates publications, grants, clinical trials, patents, and policy documents, aiming to offer a comprehensive understanding of research activity from funding to impact.
