Open Access

What is a Repository?

Open Access Repositories are freely accessible online digital archives hosting research outputs that are deposited directly by authors (known as self-archiving). Repositories are designed to store, preserve and provide access to research outputs in perpetuity. The full text content and metadata is harvestable by search engines and other discovery services.

There are two main types of Open Access Repositories:

  • Institutional Repositories - research output from a particular institution (eg DSpace@MIT)

  • Disciplinary Repositories- research from scholars in a particular discipline regardless of institutional affiliation. (eg Social Science Research Network)
