Coronavirus Updates: See latest COVID-19 news from Harvard Extension School.

By registering for a course at the Extension School, you can take advantage of many Harvard library benefits, including online access to more than 3,000 electronic databases and journals as well as on-campus access to all FAS libraries.

Online Resources

Search the HOLLIS library catalog for books, articles, and more. 

Use the Library Guide for Harvard Extension School for help with Harvard Library spaces, services, and resources, as well as research help.

If your instructor has asked you to search a particular database (for example, JSTOR) you can search for the database on the Databases website.

On-Campus Resources

All the libraries of the Faculty of Arts and Sciences (FAS) are open to active Extension School degree candidates and premedical program participants with a Harvard student ID card or currently registered Extension School students with a class participant library card.

Class Participant Library Cards

In a typical year, registered students at the Extension School are eligible for a class participant library card that allows you on-campus access and borrowing privileges at Faculty of Arts and Sciences (FAS) libraries during the terms in which you are registered. Class participant library cards provide privileges only at FAS libraries; they do not provide access to other Harvard University facilities or resources.

To reduce campus density during the COVID-19 pandemic, new and replacement class participant library cards will not be available to Extension School students for the fall 2021 or spring 2022 term. Monitor the Extension School COVID-19 updates page for all COVID-related policies.
