Yes, Sojourner Truth wrote a book called Narrative of Sojourner Truth: A Northern Slave. I think this is the only book she wrote, but I'm not sure. I'm doing a report on her and it didn't say she wrote any other books.
Yes, as it turns out, there are at least three schools, and possibly more, named after her. One is in New York City, PS 149, the Sojourner Truth School. Another, the Sojourner Truth Academy, is in Minneapolis, Minnesota. And a third is located in Oakland, California.
