CORE vs Inciteful

CORE is a multidisciplinary discovery service for scholarly work gathered from repositories, preprint servers and journals. Its search covers research papers, journal articles, preprints, theses, dissertations, conference proceedings, reports and books. CORE says its collection holds 449 million searchable papers, including 57 million full texts. Researchers and the public can search this material; developers can use the API for real-time access to metadata and full texts. The CORE Dataset supports downloading data for analysis and text mining on an organisation’s own infrastructure, though access is limited to users representing organisations registered in non-sanctioned countries. Individuals can use the API instead. CORE Discovery is available as a browser extension, repository plugin and API, and CORE Recommender suggests related articles in repositories, journal systems and web interfaces. Free API access costs nothing, subject to rate limits of one batch request or five single requests per 10 seconds. Starting membership costs nothing for data providers. The service describes itself as not-for-profit and community-governed.

Inciteful is a free web tool that helps researchers discover academic literature through citation networks. Paper Discovery builds a network around selected papers and surfaces important and similar papers, along with authors and institutions. Results can be filtered by keyword, distance, and year. Literature Connector maps citation paths between two papers in an interactive visualization, supporting interdisciplinary work and entry into unfamiliar research areas. Inciteful says its database covers more than 240 million academic papers and indexes more than 2 billion citations, using sources including OpenAlex, Semantic Scholar, Crossref, and OpenCitations. Researchers can import BibTeX files to seed a graph, provided entries include DOIs, then export results in BibTeX format or to Zotero, Mendeley, or another reference manager. Core tools are free with no stated usage limits. The maker says the codebase is fully open source. Graph Pruning is beta and may not remain supported or become permanent.
