TL;DR

• An embargo period delays public access to a published paper.

• Embargo lengths vary by journal, typically 6 to 24 months.

• Authors can often share preprints even during an embargo.

• Funder mandates can override a journal's embargo rules.

• Understanding embargoes protects your rights as an author.

You submitted your paper. It got accepted. Then someone tells you the full text will not be freely available for another 12 months. That feels strange, especially when you worked hard on the research and want people to read it.

Embargo periods are one of the least-explained parts of academic publishing. Most guides skip straight to submission tips and leave out the part where your accepted paper sits behind a paywall for a year. That gap causes real confusion for student researchers who assume acceptance means immediate public access.

This post explains exactly what an embargo period is, why it exists, how long it typically lasts, and what you can and cannot do while your paper is under embargo.

What Is an Embargo Period?

An embargo period is a set length of time after a paper is published during which the full text is not freely available to the public. The paper exists. It has a publication date and a DOI (Digital Object Identifier). But readers who do not have a journal subscription cannot access it until the embargo ends. After the embargo period closes, the paper moves to open access.

Publishers set embargo periods to protect subscription revenue. If a journal's content became freely available the moment it was published, institutions and individuals would have less reason to pay for subscriptions. The embargo gives the journal a window of exclusive access before the content becomes public.

This is separate from the question of whether a journal is open access by default. Fully open access journals, where authors pay an Article Processing Charge (APC) upfront, do not impose embargo periods. The content is free to read from day one. Embargo periods apply primarily to subscription-based journals that allow authors to self-archive a version of their paper after a waiting period.

What Is an Embargo Period in Practice for Student Researchers?

For a student researcher, an embargo period means your published paper may not be shareable in its final form for months after it appears online. The version of record, which is the formatted PDF as it appears in the journal, stays behind the journal's paywall during the embargo. What you can usually share is an earlier version of the manuscript.

Most journals that impose embargoes follow a tiered version policy. They distinguish between three versions of a paper: the submitted manuscript before peer review, the accepted manuscript after peer review but before journal formatting, and the version of record. Embargo rules typically apply to the version of record. The accepted manuscript, sometimes called the Author Accepted Manuscript or AAM, can often be deposited in an institutional or subject repository after the embargo period ends, or sometimes immediately.

For example, Elsevier's standard embargo period for most of its subscription journals is 12 months, after which authors may post the AAM to a non-commercial repository. Springer Nature applies embargo periods that range from 6 to 12 months depending on the journal and the subject area, according to their author self-archiving policies published on their website.

If you are trying to choose the right journal for your paper and want to understand how access policies affect your readers, the guide on what open access publishing means and whether it matters for you covers the broader landscape clearly.

How Long Does an Embargo Period Last?

Embargo periods typically range from 6 to 24 months, with 12 months being the most common length across major subscription publishers. The exact duration depends on the journal, the publisher, and sometimes the subject discipline. Humanities journals tend to have longer embargoes than science journals, often 24 months, partly because citation cycles in humanities are longer and subscription revenue depends on sustained access over time.

Here is how embargo lengths break down across common scenarios:

1. 6 months: Common in fast-moving fields like biomedical research, where funders such as the National Institutes of Health (NIH) in the United States require public access within 12 months and publishers set shorter embargoes to comply.

2. 12 months: The most widespread standard across science, technology, engineering, and mathematics (STEM) journals from major publishers including Elsevier, Wiley, and Springer Nature.

3. 24 months: More typical in humanities and social sciences, where journals like those published by the Modern Language Association often apply longer embargo windows.

Some journals have no embargo at all because they are fully open access. Others have embargoes that vary by country or funder. If you are a student researcher submitting to a journal for the first time, the embargo length should be one of the things you check before you submit, not after.

If you want to understand what happens to your paper once it clears the review process and moves toward publication, the post on what happens after your paper is accepted walks through each stage in detail.

What Can You Do During an Embargo Period?

During an embargo period, you retain the right to share certain versions of your work, talk about your research publicly, and in many cases post a preprint. What you cannot do is post the journal's formatted version of record on a public website or repository until the embargo ends.

Here is what is generally permitted while a paper is under embargo:

1. Share preprints: If you posted a preprint before submission, that version remains publicly accessible throughout the embargo. Preprints are not the same as the published version, so journal embargo policies do not apply to them. You can read more about this in the guide on what a preprint is and whether you should upload before submitting.

2. Email the paper directly: Most journal policies allow authors to send the full published PDF to any individual reader who requests it. This is called author-request sharing and is permitted even during the embargo window.

3. Post the accepted manuscript after embargo: Once the embargo period ends, you can deposit your AAM in a repository like PubMed Central, an institutional repository, or a subject-specific archive.

What you cannot do is post the version of record on ResearchGate, Academia.edu, or a personal website before the embargo ends. Publishers actively monitor these platforms and issue takedown requests when they find embargo violations. This matters even for student researchers because a takedown notice can complicate your relationship with the journal and affect future submissions.

How Funder Mandates Affect Embargo Periods

Funder mandates can shorten or eliminate embargo periods entirely. If your research was funded by a body that requires open access, the journal's standard embargo may not apply to your paper. This is increasingly common as governments and research councils push for faster public access to publicly funded research.

The most significant example is Plan S, a coalition of research funders in Europe that requires immediate open access for any research they fund, with no embargo period permitted. In the United States, the NIH updated its public access policy in 2023 to require that all NIH-funded research be made freely available immediately upon publication, removing the previous 12-month embargo window, according to the NIH Office of Extramural Research.

For high school student researchers, funder mandates are less likely to apply unless your project received formal grant funding. But if you are working with a university lab, a government-sponsored science programme, or an institution that has its own open access policy, it is worth checking whether any funder requirements apply to your work before you sign a publishing agreement.

Understanding the full landscape of peer-reviewed publishing, including how journals make decisions about access and review, is foundational to navigating these policies. The post on what peer-reviewed research is and why it matters gives useful context here.

What Is an Embargo Period Versus a Paywall?

An embargo period is temporary. A paywall is permanent unless the author pays an open access fee. These two things are often confused because they produce the same result from a reader's perspective: the paper is not free to access. But the underlying mechanism is different.

A paywall means the journal restricts access to subscribers indefinitely. The paper will never become freely available unless the author upgrades to open access. An embargo period means the restriction is time-limited. After the embargo ends, the author can make the accepted manuscript publicly available at no cost, even if the version of record stays behind the paywall.

This distinction matters when you are choosing where to publish. A journal with a 12-month embargo is more author-friendly than a journal with a permanent paywall and no self-archiving rights. Checking a journal's self-archiving policy through the SHERPA RoMEO database, which is a free tool maintained by Jisc, tells you exactly what each journal permits before you commit to submitting.

Frequently Asked Questions

Does an embargo period affect whether my paper counts as published?

No. A paper under embargo is fully published. It has a publication date, a volume and issue number, and a DOI. The embargo only restricts free public access to the full text. The paper's existence and citation record are not affected by the embargo period.

Can I put my paper on my personal website during the embargo period?

Generally no, not the version of record. Most journal policies prohibit posting the formatted PDF on personal websites during the embargo. You can usually post the accepted manuscript after the embargo ends. Check the specific journal's self-archiving policy before posting anything. The SHERPA RoMEO database lists policies for thousands of journals.

What happens when the embargo period ends?

When the embargo ends, you are free to deposit your accepted manuscript in a repository, post it on your personal or institutional website, and share it publicly. The version of record may still sit behind the journal's paywall, but the accepted manuscript version becomes openly shareable. Some journals automatically move the paper to open access at this point.

Do all journals have embargo periods?

No. Fully open access journals do not impose embargo periods because the content is freely available from publication. Embargo periods apply to subscription-based journals that allow delayed self-archiving. Hybrid journals, which are subscription journals that offer an optional open access route, also impose embargoes on papers where the author has not paid the APC.

How do I find out the embargo period for a specific journal?

Check the journal's author guidelines directly on its website. Most major publishers publish their self-archiving and embargo policies in the author services section. You can also search the SHERPA RoMEO database by journal name or ISSN (International Standard Serial Number) to find a summary of the journal's sharing permissions and embargo length.

Understanding Embargoes Helps You Publish Smarter

Embargo periods are not a barrier to publishing. They are a condition of publishing in certain journals, and knowing the rules before you submit puts you in a stronger position. Check the embargo length. Check what version you can share and when. If open access matters to your readers or your funder, factor that into your journal choice from the start.

The more you understand about how academic publishing works, from peer review to access policies to what makes a paper stand out, the better your decisions will be at every stage. The Publication Compass blog covers each part of that process for researchers who are new to it.
