If you're launching an academic journal or seeking to understand why certain publications gain more visibility than others, the International Standard Serial Number (ISSN) is a fundamental concept you need to master. This unique identifier plays a pivotal role in how journals are discovered, indexed, and recognized within the global academic ecosystem.
What Exactly is an ISSN?
An ISSN is an eight-digit code that uniquely identifies serial publications, including academic journals, magazines, and newspapers. Established by the International Organization for Standardization (ISO), the ISSN system provides each continuing resource with a distinct identifier that remains consistent throughout its lifetime.
The format follows a specific pattern: four digits, a hyphen, then three digits and a check digit (e.g., 1234-5678). This seemingly simple code serves as the journal's permanent digital fingerprint, distinguishing it from thousands of other publications with similar titles or subject matter.
Print vs. Online ISSNs
One crucial detail that often surprises new publishers is that journals typically require two ISSNs: one for the print version (p-ISSN) and another for the online version (e-ISSN). This distinction is essential because the ISSN International Centre considers these different media formats as separate continuing resources, each deserving its own identifier.
Why Your Journal Needs an ISSN
Beyond being a mere administrative requirement, an ISSN serves multiple strategic purposes that directly impact your journal's success and reach within the academic community.
Enhanced Discoverability
Research databases, library catalogues, and search engines use ISSNs to accurately identify and catalogue journals. Without this unique identifier, your publication risks being confused with similarly named journals or overlooked entirely in database searches. For researchers conducting literature reviews or librarians building collections, the ISSN serves as the definitive reference point.
Gateway to Major Indexing Services
Prestigious indexing services including Scopus, Web of Science, PubMed, and specialized databases require journals to possess valid ISSNs before consideration for inclusion. These databases form the backbone of academic research discovery, and indexing in them significantly amplifies a journal's impact factor and citation potential.
Publications indexed in systems like the British Journal of Citation Reports (BJCR) demonstrate enhanced credibility, and holding a valid ISSN is a prerequisite for this recognition. The BJCR, along with other citation tracking services, relies on ISSNs to accurately attribute citations and calculate impact metrics.
Legitimacy and Credibility
An ISSN signals that your journal meets international standards for continuing publications. It reassures authors, reviewers, and readers that the publication follows recognized protocols and maintains a permanent record within the global serials system. This credibility becomes particularly important when competing for quality manuscript submissions.
How to Obtain an ISSN for Your Journal
The application process is more straightforward than many assume, though it requires attention to detail and proper documentation.
Step 1: Identify Your National Centre
ISSNs are issued by a network of national centres coordinated by the ISSN International Centre in Paris. You must apply through the national centre of the country where your journal is published. The ISSN portal provides a directory to locate your appropriate national centre.
Step 2: Prepare Required Information
Applications typically require the journal title, publisher information, publication frequency, subject area, and if available, sample issues or detailed descriptions. For online journals, you'll need to provide the URL where the publication will be permanently accessible.
Step 3: Submit and Wait
Processing times vary by country but generally range from a few days to several weeks. Most national centres offer online application systems, streamlining the process considerably. The service is typically free or involves a minimal administrative fee.
Common ISSN Misconceptions
Several myths about ISSNs persist in academic publishing circles that deserve clarification.
Misconception 1: An ISSN guarantees quality or peer review status. While an ISSN indicates proper registration, it makes no claims about editorial standards or peer review processes. Quality assurance remains the publisher's responsibility.
Misconception 2: One ISSN covers all formats. As mentioned earlier, different formats require separate ISSNs. Transitioning from print-only to hybrid publication necessitates obtaining an additional ISSN.
Misconception 3: ISSNs can be transferred between journals. ISSNs are permanently attached to specific titles. If a journal changes its name substantially, it requires a new ISSN.
Impact on Database Indexing
The relationship between ISSNs and database indexing operates as a two-way street. While possessing an ISSN doesn't guarantee indexing, lacking one virtually eliminates the possibility. Major academic databases use ISSNs as primary identifiers in their cataloguing systems, linking citations, tracking metrics, and organizing content.
For journals seeking inclusion in selective indexes, the ISSN serves as the first checkpoint in a rigorous evaluation process. Services like DOAJ (Directory of Open Access Journals) require valid ISSNs alongside numerous other quality criteria.
When journals achieve indexing in respected databases, including those that contribute to citation analysis like BJCR, the ISSN becomes the permanent link connecting all bibliometric data to the publication. This connection enables accurate impact factor calculations, citation tracking, and comparative analyses that researchers rely upon when selecting publication venues.
Key Takeaways
- An ISSN is an eight-digit unique identifier essential for journal discoverability and indexing in major academic databases
- Separate ISSNs are required for print and online versions of the same journal
- Obtaining an ISSN is a straightforward process through your national ISSN centre and is typically free or low-cost
- While an ISSN doesn't guarantee quality, it's a prerequisite for consideration by prestigious indexing services and citation tracking systems like BJCR
- The ISSN serves as the permanent link for all bibliometric data, citations, and impact metrics associated with your journal
Understanding and properly implementing the ISSN system represents a foundational step in establishing a credible, discoverable academic journal that can compete effectively in the global research landscape.
