How do I search for a journal's metrics?

Simply type the journal name in the search box on our homepage. Our fuzzy search will find matching journals even if you don't spell the name exactly. You can search by full journal name, abbreviation, or keywords.

What do Q1, Q2, Q3, Q4 quartiles mean?

Quartiles rank journals within their subject subfields by Journal Metrics Score:

• Q1: Top 25% of journals (highest impact)
• Q2: 25-50% range (above average impact)
• Q3: 50-75% range (below average impact)
• Q4: Bottom 25% of journals (lowest impact)

What are CAS blocks (B1, B2, B3, B4)?

CAS (Chinese Academy of Sciences) blocks classify journals into different tiers. B1 represents the highest tier journals, while B4 represents lower tier journals. This classification is commonly used in Chinese academic institutions.

How often is the data updated?

Our journal database is rebuilt periodically from fresh OpenAlex snapshots. The current release is the August 2026 snapshot, based on 2025 citation data. We strive to provide the most current journal metrics for the current academic year.

Is Journal Metrics free to use?

Yes! Journal Metrics is completely free to use. There's no registration required, no hidden fees, and no limits on searches. Our goal is to provide accessible journal metrics for all researchers.

Can I suggest a journal to be added?

While we work to maintain a comprehensive database, if you notice a journal is missing, please contact us at admin@labcat.ai with the journal details. We'll review and consider adding it in our next update.

What if I can't find a specific journal?

Try different search terms: abbreviations, alternative names, or keywords from the journal title. If you still can't find it, the journal might not have enough citation data for a score, or it might be very new. Contact us for assistance.

Can I use this data for academic purposes?

Yes, you can use the information for academic and research purposes. However, for official submissions or formal documentation, we recommend verifying the data against the journal's OpenAlex record, publisher information, or the databases your institution designates.
