The University of Illinois Undergraduate Library offers a unique bibliographic instruction (BI) program for students enrolled in freshman rhetoric, English, or English as a second language courses. It consists of 11 different programs and 10 distinct components, each specially developed for a distinct student group. Although each BI program is different, all 11 are based on the principles that information is formally structured according to subject hierarchies, the student body is heterogeneous, and instruction is most effectively presented at the student's time of need (i.e., course-integrated). A six-point taxonomy of information skills listed in ascending order of cognitive demand or research sophistication, from physical orientation to understanding the idiosyncracies of access tools and materials within specific disciplines, has also been designed to guide the development of the program. A description of a specific program offered for the basic writer, Pre-Research Skills Instruction (PRSI), provides an example of a controlled research exercise designed by librarians and writing instructors to provide basic writers with a successful initial research experience. Appendices include "Keystones of Bibliographic Information: Hierarchical Structure of Information"; a listing of PRSI research topics; a PRSI subject bibliography; a bibliographic instruction checklist for the classroom teacher; and a seven-item bibliography of material related to librarian-English instructor cooperation.
