Serbian Citation Index (Serbian: Srpski citatni indeks; SCIndeks) is a combination of an online multidisciplinary bibliographic database, a national citation index, an Open Access full-text journal repository and an electronic publishing platform.

[4] While the content of SCIndeks is freely available to users, the publishers of the indexed journals subscribe to one of four service packages that provide various levels of content indexing and quality control: from basic bibliographic data (no full text) to full-text availability, DOI assignment, bibliometric evaluation, journal management support and plagiarism detection.

Publishers may also subscribe to SCIndeks Assistant,[6] a journal management system based on Open Journal Systems and enriched with a number of in-house developed services, tools and protocols that enable the normalization of names, affiliations and funding information; automated parsing and formatting of references; matching of references and citations; keywords assignment, etc.

SCIndeks Assistant also enables plagiarism detection through CrossRef Similarity Check, using iThenticate.

SCIndeks was originally funded by the Ministry of Science of the Republic of Serbia, which means that indexing and bibliometric analyses were free for journals.
