Abstracting & Indexing

TUJNAS is discoverable through the abstracting, indexing, and scholarly discovery services listed below, subject to the independent coverage policies and update schedules of each service. The journal reviews this page periodically and updates it when coverage is confirmed, changed, or discontinued.

Abstracting, indexing, and discovery services: Google Scholar, ResearchGate, Semantic Scholar, OpenAlex, ResearchBib, ASCI, Exaly, Discovery Researcher Life.

Persistent identifiers and metadata infrastructure: TUJNAS displays its ISSN/eISSN on the journal website and assigns Digital Object Identifiers (DOIs) to articles through Crossref. ISSN, DOI, and Crossref metadata registration support identification, citation, and discoverability; they are not presented as abstracting or indexing databases.

Indexing and discovery coverage may vary by article, issue, metadata update cycle, and the independent policies of each external service. TUJNAS does not guarantee immediate appearance of every article in every listed service. Authors and readers are encouraged to verify article-level coverage directly in the relevant service when required for reporting or institutional assessment.
