Users may also subscribe to abstracting email journals covering a range of research fields and specialties; these e-journals regularly distribute emails containing abstracts (with links where available) of newly submitted SSRN papers in that field.

Contrary to academic journals, many SSRN articles are preprints. A preprint can be defined as an author drafted version of a research manuscript that has not yet been formal published in a scientific journal. Preprints play an integral part in research - they allow authors to make their work more widely available than would otherwise be possible and help advance research without delay.

Faculty from the University of Washington are strongly encouraged to share their scholarly works on SSRN. The College of Law Library can assist faculty with posting papers to SSRN and linking them with UW Law RPS series - just fill out this form!
