Introduction to Institutional Repositories in Scholarly Spaces
Green Open Access—the practice of self-archiving peer-reviewed manuscripts in institutional repositories—is a critical, cost-effective pathway for achieving compliance with public funding mandates (such as the US Nelson Memo and Plan S).
The Role of Institutional Repositories in Open Access
Institutional Repositories (IRs) are university-managed digital archives designed to capture, preserve, and showcase the institution’s intellectual outputs. IRs host preprints, accepted manuscripts (postprints), theses, and datasets, providing free, open-access alternatives to paywalled journal versions.
Navigating Publisher Embargoes and Permissions
To self-archive legally, authors must understand publisher copyright agreements. Many traditional journals allow researchers to post their ‘Author Accepted Manuscript’ (AAM) to an IR, but apply an embargo period (e.g., 12 to 24 months) during which the manuscript cannot be made public.
Automating Self-Archiving and Metadata Harvesting
To maximize deposit rates, universities integrate IR software with payroll, CRIS, and scholarly APIs. When a publication is detected in databases like Crossref, the system automatically prompts the author to upload their accepted manuscript, utilizing protocols like OAI-PMH to syndicate metadata worldwide.
Key Data and Comparative Metrics
| Manuscript Version | Definition | Standard Open Access Permissions |
|---|---|---|
| Preprint | Submitted manuscript prior to peer review. | Generally allowed to be shared publicly on any repository, any time. |
| Postprint (AAM) | Peer-reviewed, accepted text, without publisher formatting. | Usually allowed in Institutional Repositories after an embargo period. |
| Version of Record (VoR) | Final published PDF with journal branding and layout. | Generally prohibited from repository deposit without an open access license. |
