What indexing is, when to apply, and how to prepare your website, your articles and your author base. A plain-English guide for editors and journal owners — no jargon, with a readiness checklist at the end.The basics
What indexing is & why it matters

An index (or database) evaluates academic journals against a set of quality criteria and lists those that qualify. Once a journal is indexed, its articles become far easier for researchers to discover, are more likely to be cited, and the journal earns greater trust within the scholarly community.

In short, being indexed grows three things: visibility (your articles surface in searches), credibility (an independent body has vetted your journal) and your readership and author pool (a journal in a respected index attracts stronger submissions).

A common confusion: not every index carries the same weight. Automatic discovery services like Google Scholar include almost everyone and are not a mark of quality. Editorially reviewed databases like DOAJ, Scopus, Web of Science, PubMed/MEDLINE and EBSCO are the ones that signal real credibility.

Classification
Types of indexes

To plan a sensible strategy, it helps to think of indexes in four broad groups:

A  Discovery crawlers
Automatic, no application needed. E.g. Google Scholar. Good for visibility, but not proof of quality.
B  Open-access directories
Measure open access & transparency. E.g. DOAJ. For most journals this is the first serious target.
C  Citation / quality databases
The most selective tier. E.g. Scopus, Web of Science (SCIE, SSCI, ESCI). Full editorial review.
D  Subject databases
Focused on one field. E.g. PubMed/MEDLINE (health), EBSCO collections, ERIC (education), EconLit.

Mindset
Don’t wait for perfection to start

One of the most common questions we receive is some version of: “Do I need everything — the website, the policies, the indexing — ready before I launch the journal?” The answer is no, and waiting for that is the single biggest reason journals never get off the ground.

Indexing is not a prerequisite for publishing — it is a reward for publishing well, consistently, over time. No major index will even consider a journal that has not yet published. So the order is the opposite of what many people imagine:

1
First
Set up the website & the journal
Get a proper journal platform (e.g. OJS) running, with your core pages and policies in place. This is the foundation — it does not need to be flawless on day one.
2
Then
Publish your first issue (≈5+ articles)
Run real submissions through peer review and release your first issue with a meaningful number of articles. This proves the journal is alive and working.
3
Early on
Apply for and obtain your ISSN
Register with your national ISSN centre and get your number (preferably an e-ISSN). Almost every index requires it, so do this as soon as you are publishing.
4
From here on — in parallel
Keep publishing while preparing for indexes
This is the key idea: run two tracks at once. On one track you prepare and publish the next issue on schedule; on the other you steadily strengthen policies, metadata, DOIs and author diversity so you are ready to apply to DOAJ, then Scopus / Web of Science and beyond.
The takeaway: launch first, publish consistently, and build toward indexing as you go. A journal with two solid published issues and growing is far closer to indexing than a “perfect” journal that has never released a single article.

Timing
When to apply

Applying to a major index too early — before the journal has matured — usually ends in rejection. Worse, some indexes impose a waiting period (often 6–12 months) before you can reapply. So timing matters. You are generally in good shape to apply once most of the signals below are true:

✓You have a valid ISSN.

Preferably an e-ISSN; your journal should be listed on portal.issn.org.

✓You have a real publishing track record.

A common expectation: roughly a year of regular publishing, and at least 5 peer-reviewed research/review articles per year (DOAJ’s minimum volume).

✓Your publication schedule is consistent.

Issues appear on time, without long gaps. Irregularity is one of the most common rejection reasons.

✓Your policy & masthead pages are complete.

Peer review, ethics, copyright, open access and editorial board are all published on the site.

✓Your content isn’t single-author or single-institution.

Submissions from different institutions — and ideally different countries — have started to come in.
Practical advice: set your targets in stages. With a new journal, don’t go straight for Scopus — first build Google Scholar visibility and prepare for DOAJ. That groundwork is exactly what the top-tier indexes look for later.

Preparation · 1
Website & transparency

Almost every index shares one expectation: who the journal is, how it works and what it promises must be clearly stated on the site. Reviewers typically visit your website first. Make sure each of the following is present, clear and up to date:

✓Journal name & identity

A unique, non-misleading name shown consistently on the homepage and the “About the Journal” page.

✓Editorial board

Members listed with name, affiliation, country and ideally academic profile links (ORCID, institutional page).

✓Author guidelines & submission rules

The submission process, formatting requirements and ethical criteria spelled out in detail.

✓Peer review process

State clearly which type of review you use (e.g. double-blind). All content must be reviewed.

✓Publication ethics policy

How you handle plagiarism, conflicts of interest and misconduct — ideally referencing COPE guidelines.

✓Open access & copyright policy

Whether access is free, and who holds copyright (e.g. an appropriate Creative Commons licence).

✓Publication frequency

How often the journal is published (e.g. 2 or 4 issues per year) must be clearly stated.

✓Ownership & management

The owner/publisher and contact details should be visible.

✓A healthy website

No broken links, no inaccessible PDFs, no outdated information. This shows the journal is actively maintained.
Note: If you run OJS, most of these are configured under Settings → Journal / Website / Workflow. The structure already follows the standards — your job is simply to fill in every field completely and consistently.

Preparation · 2
Article quality & technical standards

Indexes judge a journal not only by its policies but by the content it actually publishes. There are two dimensions: the scholarly quality of the work, and its technical/metadata hygiene.

Scholarly quality

Original, peer-reviewed articles with clear methods and proper references. A balance weighted toward original research (rather than mostly reviews or translations) is preferred. Every published item must genuinely have passed peer review.

Technical & metadata standards

✓English metadata

Even for non-English articles, provide an English title, abstract and keywords — critical for international indexes.

✓DOI assignment

A persistent identifier (Crossref DOI) for every article is a strong plus.

✓Full-text access

Each article must be individually accessible, downloadable and directly linkable — a single bundled PDF is not enough.

✓Clean references

A consistent citation style and, where possible, DOI links in the reference list.

✓Machine-readable format

HTML and/or JATS XML full text makes it far easier for indexes to harvest your content.
Tip: Crossref membership and DOI assignment, metadata sharing via OAI-PMH, and HTML/JATS XML full text — these three put you ahead of competing journals when you move up to the top-tier indexes.

Preparation · 3
Author & country diversity

Something many journal owners overlook — but which the top-tier indexes (especially Scopus and Web of Science) take seriously: showing that your journal is an international scholarly platform, not a local bulletin. Diversity is how you prove it.

i  Author diversity
Articles shouldn’t all come from one institution or the same small group of authors. Contributions from a range of universities break the “closed journal” perception.
ii  Geographic spread
Authors from more than one country, where possible. International contribution is the clearest sign of genuine global interest.
iii  Editorial board diversity
A board drawn from several institutions and countries, made up of recognised names in the field.
iv  Reviewer pool
A broad, independent pool of reviewers demonstrates the impartiality of your review process.
Why it matters: indexes are wary of closed journals where a handful of people publish each other’s work. Diversity signals impartiality, reach and real academic impact. Build it authentically — by genuinely promoting your journal internationally — not through artificial shortcuts.

Strategy
Which index to start with

The healthiest path is to climb the indexes in order, as your journal matures. This staged route works for most journals:

1
Visibility · Immediately
Google Scholar & basic crawlers
No application needed; if your site is configured correctly it is crawled automatically. Gives early visibility and lets citations start to accumulate.
2
First serious target · After ~1 year
DOAJ (Directory of Open Access Journals)
Proves your open-access and transparency standards. Expects roughly a year of publishing or 5+ research articles per year, a clear licence and complete policy pages. A strong stepping stone toward higher indexes.
3
Databases & your field
EBSCO & subject databases
Aggregators like EBSCO and discipline-specific databases — e.g. PubMed/MEDLINE for health sciences, ERIC for education — are realistic mid-stage targets that widen your reach within your field.
4
Top tier · Mature journals
Scopus & Web of Science
The most selective targets. They require consistency, international author and board diversity, citation performance and complete metadata. Apply here only after you’ve solidly cleared the lower rungs.

Watch out
Common mistakes
×Waiting until everything is “perfect” before launching — instead of publishing and improving in parallel.
×Applying to major indexes too early, with thin or incomplete content.
×Policy pages (ethics, peer review, copyright) that are missing or contradict each other.
×Broken links, inaccessible PDFs and outdated information.
×Missing English abstracts and keywords.
×Content limited to a single institution or author group.
×An irregular publication schedule with delayed issues.
×Paying to be “listed” by predatory indexes and mistaking it for real indexing — it costs you credibility.
Golden rule: if an index asks for a fee but performs no genuine editorial review, stay away. Reputable databases evaluate your content — they don’t sell you a spot on a list.

Summary
Am I ready? Quick checklist

If you can answer “yes” to all of the following, you are most likely ready to apply:

✓You have a valid ISSN and an ISSN Portal listing.
✓You’ve published for ~1 year, or have 5+ peer-reviewed articles per year.
✓Ethics, peer-review, copyright and open-access policies are complete on the site.
✓The editorial board is listed with affiliation and country.
✓Articles carry English abstracts + keywords and, ideally, DOIs.
✓Every article has full-text access and there are no broken links.
✓Content comes from varied institutions/authors; international contribution has begun.
✓Your publication schedule runs on time, without gaps.

From Print to Digital: PDF, HTML, or XML – What Should Academic Journals Publish Today?

✇OPEN JOURNAL SYSTEM SERVICES

A practical guide for journal editors navigating the format transition in scholarly publishing

Over the past year, our team at FullTextCreator has been building a system that converts academic article PDFs and Word documents into full-text HTML and JATS XML. We built it because the demand was there — and it keeps growing.

Journals want to publish in multiple formats. Indexing databases increasingly require structured content. Authors expect their work to be discoverable, readable, and citable across platforms. And yet, when we process hundreds of articles from dozens of journals, we keep seeing the same reality: most academic content is still locked inside PDFs designed for a printer that doesn’t exist anymore.

This post is about why that matters — and what to do about it.

If you’re looking for practical guidelines on how to prepare a well-structured academic PDF, we’ve already written a detailed guide on creating machine-readable academic PDFs. Consider that a companion piece to this one.

PDF: A Tool Designed for Print

The PDF format was created in the early 1990s to solve a very specific problem: how do you ensure a document looks exactly the same on every screen and every printer, regardless of operating system or software? The answer was to freeze the layout — to treat the page like a photograph.

For print publishing, this was revolutionary. For digital-first academic publishing, it’s increasingly a limitation.

A PDF is a visual container. It knows where every word is on the page. It does not know that a bold centered line is a section heading, that a superscript number is a citation, or that a block of indented text is an abstract. Machines can see a PDF, but they cannot easily understand it.

This matters more than ever. The academic ecosystem now includes:

  • Search engines that need to parse and rank your content
  • Indexing databases (PubMed, Scopus, Web of Science) that need to extract metadata
  • AI-powered research tools (Semantic Scholar, ResearchRabbit, Perplexity, Elicit) that need to read and summarize full text
  • Reference managers (Zotero, Mendeley) that need to extract citations
  • Accessibility tools that need to serve content to readers with visual impairments
  • Translation pipelines that need clean, structured text

PDF can serve some of these purposes — but only if the PDF itself is carefully structured. In most cases, it serves none of them particularly well.

We Are in a Transition Period

Let’s be honest: PDFs are not going away. And for good reasons.

Many indexing requirements still mandate a PDF full-text submission. TR Dizin, for example, requires a PDF. Several EBSCO and DOAJ policies are built around PDF availability. Authors are accustomed to downloading and sharing PDFs. Peer reviewers expect them. Citation managers import them. Institutions archive them.

More importantly: the habits of a generation of academics are built around the PDF paradigm. You cannot simply replace it overnight, even if you wanted to.

What we are seeing — across PKP’s Open Journal Systems community, among Scopus-indexed journals, and among publishers preparing for PubMed Central submission — is a gradual shift toward multi-format publishing. The PDF stays, but it is no longer alone. Alongside it:

  • A full-text HTML version optimized for browser reading
  • A JATS XML file for databases and long-term interoperability
  • Sometimes an ePub for mobile reading apps

This is not a radical proposal. It is what Nature, PLOS, eLife, and virtually every major academic publisher already does. The question for smaller and mid-sized journals is: when do we start, and how?

The Case for Full-Text HTML

HTML is how the web was built. It is what browsers read natively. And it has specific advantages for academic content that are easy to underestimate.

Readability without a download. A reader on a mobile phone can open an HTML article directly in their browser. No app needed, no 5MB file to download, no PDF viewer struggling to reflow text for a small screen. On mobile — which now accounts for a significant portion of academic reading — HTML wins by a large margin.

Better indexing by search engines. Google Scholar, Bing Academic, and general web crawlers index HTML content more accurately and more completely than PDFs. Headings, keywords, abstracts, author names, and citations embedded in structured HTML are more reliably extracted and ranked.

Accessibility. Screen readers, browser zoom functions, contrast settings, and dyslexia-friendly fonts all work seamlessly with HTML. PDF accessibility requires additional tagging work that most journals skip entirely.

Linking and interactivity. HTML enables clickable reference lists, internal section links, embedded figures with captions, supplementary material expansion, and DOI links that work inline. A PDF is static; HTML is alive.

Compatibility with AI research tools. Tools like Elicit, Consensus, Semantic Scholar, and even general-purpose LLMs process text far more accurately when it is clean HTML than when it is extracted from a PDF. As AI-assisted literature review becomes standard in academic workflows, HTML-published content will have a measurable advantage in discoverability and citation.

The Case for JATS XML

JATS (Journal Article Tag Suite) is the XML standard used by PubMed, PMC, Crossref, and most major academic databases for structured article exchange. If HTML is the format for readers, JATS XML is the format for machines and systems.

PubMed Central requires it. If your journal is applying for or maintaining PubMed/PMC indexing, JATS XML is mandatory. There is no workaround.

Metadata richness that PDF cannot match. A JATS XML file can encode author ORCID IDs, funding information with Funder Registry identifiers, contributor roles (CRediT taxonomy), structured reference lists with DOIs, figure descriptions, license terms, and dozens of other metadata fields — all in a machine-readable, standardized way. This is the difference between having metadata and communicating it to every system that touches your content.

Portability and long-term interoperability. JATS XML is format-agnostic. From a single well-formed XML file, you can generate HTML, PDF, ePub, or any future format. It is the master record from which everything else can be derived. This is why major publishers maintain JATS XML as their canonical content format.

Future-proofing for AI and data mining. Academic data mining — the large-scale analysis of scientific literature for trends, systematic reviews, and AI training — operates almost entirely on structured XML. Journals that publish JATS XML contribute to and benefit from this ecosystem. Journals that publish only PDF are largely invisible to it.

Crossref metadata deposit. When you register a DOI with Crossref, the metadata you deposit determines how well your article is matched in citation indexes. JATS XML enables richer, more accurate Crossref deposits than manual metadata entry.

What About Metadata? The Invisible Foundation

One pattern we see repeatedly in our conversion work: journals that are eager to publish HTML or XML, but whose source PDFs are missing the very metadata that makes structured publishing possible.

No ORCID IDs for authors. No clear received/accepted dates. No DOI on the first page. References without DOIs. Keywords buried in the abstract text without a clear label.

Structured formats are only as good as the data that goes into them. Before investing in HTML or XML publishing, it is worth auditing your current PDF production workflow against a basic metadata checklist. We wrote that checklist here: Creating Machine-Readable Academic PDFs.

A Practical Path Forward

For most journal editors reading this, the question is not philosophical — it is operational. You have a small team, a limited budget, and a backlog of articles to process. Here is a realistic framework:

Step 1: Fix the PDF first.
A well-structured PDF with complete metadata is the foundation. If your PDF production is inconsistent, HTML and XML outputs will inherit those problems. Use the checklist linked above.

Step 2: Add HTML for current issues.
Full-text HTML for new articles is achievable with existing tools. OJS supports HTML galley uploads natively. Even a basic, clean HTML version is a significant upgrade over PDF-only publishing.

Step 3: Pursue JATS XML for indexing goals.
If your journal is targeting PubMed, pursuing higher Scopus standing, or preparing a Plan S compliance statement, JATS XML is the path. This is more complex, but the infrastructure exists to support it.

Step 4: Don’t do it manually.
Manual conversion of PDFs to HTML or JATS XML is slow, expensive, and error-prone. Automation — whether through your own typesetting workflow, a conversion service, or a platform like FullTextCreator — is the only scalable approach.

Why We Built FullTextCreator

This is not a theoretical discussion for us. We built FullTextCreator precisely because we saw how much friction existed between a journal’s content and its full digital potential.

The service accepts PDF or Word document uploads and produces clean full-text HTML and JATS XML — structured, metadata-rich, and ready for OJS galley upload or database submission. The demand since launch has been consistent and growing, particularly from journals in Turkey, Eastern Europe, and Southeast Asia that are navigating indexing requirements for the first time or preparing PMC applications.

The problem we keep solving is the same: a journal has years of well-written, peer-reviewed content, but it is locked in PDFs that no database can properly read. Format conversion is the bridge between the content that exists and the visibility it deserves.

Conclusion

The academic publishing format question is not PDF versus HTML versus XML. It is PDF plus HTML plus XML — a multi-format strategy that serves readers, machines, indexing databases, and AI tools simultaneously.

PDF remains essential for the foreseeable future. But journals that publish only in PDF are leaving discoverability, accessibility, and indexing potential on the table. The transition is already underway at every level of the scholarly publishing ecosystem. The question is not whether to make the shift, but how to do it efficiently.

For journals serious about visibility, indexing, and future-proofing their content: the format upgrade is not optional. It is infrastructure.
