What Is SSRN and How to Use It to Read Papers for Free

SSRN, originally the Social Science Research Network, is a website where researchers post papers before, or instead of, publishing them in a journal. It began in 1994 as a service for economists and has grown into one of the largest free collections of working papers in economics, finance, law, management, accounting and the wider social sciences, with newer networks for the humanities and some sciences. If you are looking for a free copy of a paper in one of those fields, SSRN is often where it lives.

Who owns SSRN

SSRN was founded by the financial economist Michael Jensen and run independently for over twenty years. In 2016 it was bought by Elsevier, the publisher that also runs ScienceDirect and Scopus. The purchase worried some researchers, but the basic deal has not changed: posting a paper is free, and reading one is free. Elsevier now describes SSRN as its preprint service.

What SSRN contains

Most papers on SSRN are working papers: drafts that the authors circulate for comment while the paper is under review or before they submit it. Economists and legal scholars have shared drafts this way for decades, and a working paper can be the citable version of a result for a year or more before the journal article appears. SSRN also holds:

• Accepted manuscripts and, where the publisher allows it, published articles that authors have uploaded
• Conference papers and book chapters
• Law review articles, which in the US are often posted in full because the student-run journals that publish them allow it
• Papers that were never published anywhere else

Papers are organised into subject networks, such as the Economics Research Network or the Legal Scholarship Network, and into "eJournals" that email subscribers new papers in a narrow topic. Nothing on SSRN has been peer reviewed by SSRN itself; a paper is checked for scope and basic standards before it appears, and that is all. See how to tell whether an article is peer reviewed.

Is SSRN free?

Reading abstracts is free with no account. Downloading the PDF is free too, but SSRN asks you to create a free account, and after a download or two without one it will insist. The account costs nothing and brings no obligations; it mainly lets SSRN count downloads, which it reports back to authors and uses for its rankings. Some papers show "Download This Paper" greyed out because the author has withdrawn the file or the publisher's rules do not allow it; in that case only the abstract is available.

How to search SSRN

Go to ssrn.com and use the search box at the top. It takes a title, an author's name, keywords or an SSRN abstract number. Results can be sorted by date or by downloads, and filtered by network. Each paper's page shows the abstract, the date posted, the number of versions and the download button.

Two alternatives are often quicker:

• Google Scholar indexes SSRN, so searching the paper's title shows the SSRN copy alongside the published version. Our guide covers finding free PDFs on Google Scholar.
• Our finder accepts the published article's DOI, link or title and lists any free copy the open-access indexes know about, including SSRN copies when the DOIs have been linked.

Every SSRN paper has an abstract number in its address, after "abstract_id=", and most have a DOI of the form 10.2139/ssrn.number. Either identifies the paper reliably; our guide explains what a DOI is and where to find it.

Finding the published version

An SSRN working paper may have been revised substantially before publication: results get re-checked, sections get cut, and sometimes the title changes. Before relying on or citing a working paper, check whether a published version exists.

The paper's SSRN page often says so. Authors can add a note such as "Forthcoming in the Journal of Finance" or a reference to the published article, and many update the title to match. If there is no note, search the title and author in Google Scholar and look for a journal entry. The published version may be paywalled; paste its DOI into the finder to see whether a free copy exists, and read preprints vs published papers for what tends to differ between the two.

How to cite an SSRN paper

Cite what you read. If you used the working paper, cite it as a working paper, with the date of the version you read, and do not present it as the journal article. A typical reference gives the authors, the year, the title, "SSRN working paper" or "Working paper", and the URL or DOI:

• Smith, J. and Lee, A. (2025) "Title of the paper", working paper, SSRN. https://ssrn.com/abstract=1234567

Legal citation styles such as the Bluebook have their own form for SSRN papers, as do APA and Chicago; see how to cite a research paper for the main styles. If a published version exists and you have read it, cite that instead.

Posting your own paper

If you are a researcher, you can create a free author page and upload your own working papers and, where your publisher allows it, your accepted manuscripts. Check the journal's policy on sharing first; our guide to the kinds of open access explains what publishers usually permit. Posting on SSRN gets a paper read and cited earlier, and it means that anyone who later hits the journal's paywall has somewhere free to go.
