Researchers for Authors and Writers I believe there is, but it is a very specialized field and the competition is likely to be stiff. I typed "work at home jobs for researchers" into Google and received 3,000,000 hits, so you may find some information there (I assume you want to work at home?). Many writers need research done; I can't imagine the better ones doing that task themselves.
If you are lucky and find work, it is important to establish a good working relationship with the person you are working for. Bear in mind that your research may uncover things that he/she had not expected or is uncomfortable with.
