The Society maintains a collection of research instruments and research protocols that are frequently used in empirical studies of literature. Because some of these materials are copyrighted, access in a few cases is restricted to members of specific research coalitions. An overview of these materials is provided below. Please navigate to the specific research coalition web pages for more details.
