Difference Between SCI Journals And SCIE Indexed Journals?SCI (Science Citation Index) and SCIE (Science Citation Index Expanded) are both databases created by Clarivate Analytics that index scientific journals. The main difference between SCI journals and SCIE indexed journals lies in the extent of coverage and citation tracking.

1. SCI Journals: The Science Citation Index (SCI) is the original database launched in 1964. It initially focused on high-impact, influential scientific journals across various disciplines. SCI journals cover a wide range of scientific fields and are considered prestigious and well-established. They undergo a rigorous selection process based on their scholarly contributions, impact, and quality.

2. SCIE Indexed Journals: The Science Citation Index Expanded (SCIE) is an expansion of the SCI database that was introduced in 1997. SCIE includes additional journals that meet certain quality criteria but may have a slightly lower impact compared to the core SCI journals. SCIE expanded the coverage of SCI to include more specialized and emerging research areas. Journals indexed in SCIE are recognized for their scientific rigor and contribute to the scholarly literature in their respective fields.

The key points to note are:

- SCI journals are considered more prestigious and typically have higher impact factors compared to SCIE indexed journals.

- SCI journals tend to cover a broader range of scientific disciplines, while SCIE indexed journals focus on specialized and emerging research areas.

- Being indexed in either SCI or SCIE indicates a journal's inclusion in the Science Citation Index database and its ability to track citations, which enhances visibility and impact.

It's important to note that individual journals may be indexed in either SCI or SCIE, or even both databases. Researchers should consider the relevance, scope, and impact of the specific journals they are targeting for publication, rather than solely focusing on whether they are indexed in SCI or SCIE.
