SSRN (Social Science Research Network) is a platform where researchers post working papers, conference papers, and other early-stage or already-published scholarship for free public access, organized around subject-specific research networks rather than a single editorial process. It is one of the largest repositories of its kind in economics, law, finance, and the wider social sciences, and it now sits inside Elsevier’s publishing infrastructure as a commercially owned platform. This guide explains what SSRN is, how posting to it actually works, how its subject networks are organized, and how it differs from a peer-reviewed journal. For help deciding between SSRN and a comparable repository for a specific submission, see arXiv vs. SSRN: Preprint and Working Paper Repositories Compared, which weighs the two platforms against each other; this page instead focuses on how SSRN itself works, on its own terms.
What SSRN Is and Who Owns It
SSRN was founded in 1994 in Rochester, New York, as a repository and online community built around social-science research. Elsevier, part of the RELX Group, acquired SSRN in May 2016. That makes SSRN, unlike a nonprofit or university-hosted preprint server, a platform operated inside a for-profit publisher’s commercial infrastructure, even though posting and reading remain free to authors and users. SSRN describes itself as an open access research platform used to share early-stage research, track its reach through download and citation metrics, and connect scholars across the applied sciences, health sciences, humanities, life sciences, physical sciences, and social sciences — though its historical core, and the bulk of its content, remains economics, law, finance, and management scholarship.
What You Can Post to SSRN
SSRN’s scope is deliberately broader than the word “preprint” implies. Alongside preprints of not-yet-published articles, authors can post working papers, conference papers, book chapters, gray literature, and, on many of its networks, papers that have already been accepted or published elsewhere and are being posted for wider visibility. This is a genuine, longstanding feature of how SSRN is used, not a loophole: in law and finance scholarship in particular, posting a paper to SSRN — often well before, and sometimes regardless of, eventual journal placement — has long been a routine step in circulating research and establishing priority. This is one of the clearest practical differences from a discipline like physics or mathematics, where a preprint server such as arXiv is used almost exclusively for not-yet-published work in something closer to preprint form.
How SSRN’s Subject-Matter Research Networks Work
Rather than organizing content into broad disciplinary categories the way arXiv does, SSRN classifies each submission into one or more subject-specific research networks and their associated eJournals — for example networks covering economics, corporate governance, financial economics, legal scholarship, management, political science, and health economics, among dozens of others. Authors self-classify at submission time, choosing at least one and up to seven subject classifications for a given paper. Each classification determines which eJournal(s) the abstract is distributed through and which subscribers receive an email alert when it’s posted. Over time, the abstracts distributed to a given eJournal accumulate into that eJournal’s “eLibrary,” effectively a running archive of everything classified under that topic. Many law schools, business schools, and economics departments also run their own institutional working-paper series through SSRN, giving a faculty’s output a dedicated eJournal alongside the general subject networks.
SSRN also aggregates download and citation counts into rankings — author, institution, and paper rankings by downloads within a given network or eJournal — which some fields treat as a visible, if informal, measure of early reach. These download-based metrics are a readership signal, not a quality signal in the way peer-reviewed citation counts are sometimes treated; a highly downloaded SSRN paper has not thereby been vetted for correctness.
How the Submission and Review Process Works
Posting to SSRN is free for authors, both for the initial submission and for ongoing distribution through eJournal alerts. After a paper is uploaded, it is not published immediately: SSRN staff review the submission before public release, checking that it fits the platform’s scope and meets basic formatting and legitimacy standards. Staff may edit or query an abstract, and will occasionally reject a submission judged insufficiently scholarly, but this screening is administrative, not peer review — it does not evaluate the soundness of the paper’s methods, evidence, or conclusions. Authors are notified by email once a submission has been processed or if the SSRN team has questions. Authors can subsequently revise and re-post a paper, and prior versions typically remain associated with the record.
How SSRN Differs From a Peer-Reviewed Journal
The distinction that matters most for readers and for tenure/promotion committees is that SSRN screening and journal peer review are not the same process and are not interchangeable. A paper’s presence on SSRN indicates only that it passed an administrative scope-and-format check, not that independent subject-matter experts assessed its methodology, evidence, or conclusions. Concretely:
- What’s checked. SSRN checks scope, format, and basic scholarly legitimacy. A journal’s peer review process checks the substance — methods, evidence, framing, and contribution — typically through two or more subject-expert reviewers before an editorial accept/reject decision.
- What’s accepted. SSRN accepts working papers, conference papers, and already-published work for wider distribution, alongside true preprints. A peer-reviewed journal publishes only work that has cleared its own review and editorial process, once, in a specific, versioned form.
- What changes after posting. An SSRN posting can be revised by the author at will. A published journal article is fixed at publication; subsequent corrections go through a formal correction, erratum, or retraction process (see CASRAI’s guide on writing a retraction statement).
- What it signals. An SSRN posting signals early circulation and claims priority on an idea. Journal publication signals that the work has cleared a specific venue’s editorial and peer-review bar, which is what most funders, hiring committees, and citation indexes treat as the more defensible evidentiary standard.
Researchers citing an SSRN-hosted paper, or being evaluated on the basis of one, should be explicit about which of these two states a given paper is actually in — a “posted on SSRN” working paper and a “forthcoming in [journal]” version of the same paper are not equivalent claims, even when the text is largely the same. See CASRAI’s guide on how to cite a preprint for citation format conventions that keep this distinction visible in a reference list.
SSRN and Elsevier: What the Ownership Relationship Means
Elsevier’s 2016 acquisition of SSRN means the platform’s infrastructure, and ultimately its editorial and policy decisions, sit inside a commercial publisher rather than a nonprofit or university consortium — a structurally different arrangement from arXiv, which is run as an independent nonprofit. In practice, this has not changed SSRN’s core proposition: posting and access remain free, and SSRN continues to host working papers regardless of where, or whether, they are eventually journal-published, including in journals unrelated to Elsevier. It does mean that a single commercial publisher now controls a significant share of social-science preprint and working-paper infrastructure, which is worth being aware of when weighing SSRN against an independently governed alternative for a specific submission, deposit mandate, or long-term availability commitment.
SSRN vs. arXiv: Choosing Between Them
SSRN and arXiv both let researchers share work outside the journal system, but they differ in ownership (commercial vs. nonprofit), disciplinary center of gravity (social sciences and law vs. physics, math, and computer science), and what they accept (working papers and already-published work vs. preprints proper). For a full side-by-side comparison across ownership, moderation, content types, and use cases, see arXiv vs. SSRN: Preprint and Working Paper Repositories Compared. If you’re choosing among preprint servers more broadly, CASRAI’s guide to choosing a preprint server and the institutional repository vs. subject repository comparison cover the broader decision framework.
Frequently Asked Questions
Is SSRN peer reviewed?
No. SSRN staff screen submissions for scope, format, and basic scholarly legitimacy before posting, but that screening is not peer review and does not evaluate methodological or substantive soundness. Treat an SSRN posting as early circulation, not as evidence a paper has been independently vetted.
Is it free to post a paper on SSRN?
Yes. There is no fee to submit an abstract or paper to SSRN, and no fee for the email alert distribution that comes with being classified into an eJournal.
Can I post a paper to SSRN that’s already been published elsewhere?
In many of SSRN’s networks, yes — unlike a preprint server that only accepts not-yet-published work, SSRN routinely hosts papers already accepted or published in a journal, posted for wider visibility. Whether this is appropriate for a specific paper depends on the publishing journal’s own self-archiving or green open access policy and any co-author or funder agreements, so check those before posting a published version.
Does Elsevier own SSRN?
Yes. Elsevier, part of the RELX Group, acquired SSRN in May 2016. Posting and reading remain free, but the platform’s infrastructure is owned and operated by a commercial publisher rather than a nonprofit consortium, which distinguishes it from independently governed repositories such as arXiv.
What is an SSRN “eJournal” or research network?
An eJournal is a subject- or institution-specific distribution list and archive within SSRN. When you classify a submission under a topic, it’s distributed to that eJournal’s subscribers as an email alert and added to that eJournal’s eLibrary, an ongoing archive of everything classified under that topic. Authors can select up to seven classifications per paper.
How is SSRN different from arXiv?
SSRN is commercially owned (Elsevier), centers on social sciences, law, and finance, and accepts working papers and already-published work alongside preprints. arXiv is run as an independent nonprofit, centers on physics, math, and computer science, and accepts only preprints and e-prints under a stricter endorsement system. See arXiv vs. SSRN for a full comparison.
