On1Foot can help you easily create source sheets of Jewish texts on a variety of social justice issues. [Their name is an homage to the famous story of Hillel, in which Hillel guides a student who is looking to learn the entire Torah very efficiently, while standing on one foot.] On1Foot has a robust library of Jewish texts, including a large number of commentaries from the American Jewish World Service. You can find texts about many different social justice topics, including civil rights, the environment, tikkun olam, poverty and immigration, to name just a few. You can also specify the types of Jewish texts you are looking for like rabbinic, biblical or modern and whether you are searching for prayers, commentaries or stories.
