What is Open Access?

graphic briefly explaining open access: free, immediate, online, availability, etc.

Open Access (OA) refers to works that are freely available without embargo (a waiting period) licensed with re-use rights, such as sharing, revising, and transforming. Most OA works are licensed under Creative Commons licenses.

For information seekers such as students and researchers, OA means unrestricted access to the research you need, without the use of a library proxy server or paying money to a publisher.

Institutional Repositories

Many publishers will allow institutions to archive their faculty's and staff's works, making them open access. Swarthmore College is a part of the Digital Commons Network, a network of institutional repositories. Our repository is called Works.

You can use the Digital Commons page to search across all DC institutional repositories. A search for "marijuana" brings up over 20,000 results.
