Stony Brook University

Researching Without an SBU ID

This guide is meant to help high school and other community groups who are looking for freely available high quality research materials, such as peer-reviewed journal articles.

What is Open Access?

At Stony Brook University Libraries, we subscribe to a large number of resources that are behind a “paywall,” and therefore expensive or inaccessible to the general public. SBU faculty, staff, and students have access to these databases, and when you come to campus for an instruction session, we are also able to allow you temporary guest access while you are in the computer lab during the instruction session. Unfortunately, you will not have this same access when you leave campus.


However, there are an increasing number of opportunities for the public to access peer-reviewed journal articles, dissertations, historical materials, and other resources for free through “open access” initiatives. If you are not able to come to campus, or, if you would like to find these resources after your visit, here are some freely available ways to find high quality academic resources.
