How do I know if my journal is SCI or SCI?

Excuse me, could you please clarify your question a bit further? Are you asking how to determine if your journal is included in the Science Citation Index (SCI) or the Science Citation Index Expanded (SCIE)? These are two distinct indices that are often used to evaluate the impact and quality of academic journals in various fields, including those related to cryptocurrency and finance. If so, there are a few ways to find out. One way is to check the official website of the Clarivate Analytics, which manages the SCI and SCIE indices. They provide a searchable database of journals that are included in these indices. You can also check with the editor or publisher of your journal to see if they have any information about their inclusion in the SCI or SCIE. Additionally, some academic libraries or institutions may have access to subscription-based services that provide information about journal inclusion in these indices. Can you tell me a bit more about your specific situation, and I'll be happy to provide more targeted advice?
