It's 10 a.m. in Aurora, Colorado, just outside of Denver, and the Grandview High School library is bursting with life. Its two classrooms, each equipped with state-of-the-art technology, are overflowing with kids. In one, Patricia Holloway, the library coordinator, is introducing a group of entering freshman to the library. In the other, media specialist Marcia Wolfe is working with a 10th-grade English class on a research project. Nearby, in the center of this vibrant 15,000-squarefoot space--the site of 600 library classes a year--a third class is huddled around their teacher, discussing a novel. It's even buzzing in the librarians' office, where Evelyn Scott, the third librarian-teacher--yes, the third in this 2,600-student school--is conferring with English teacher Vernal Pope about a project they created last summer for an 11th-grade AP class. By any measure--from circulation of the 44,000-item collection to impact on learning to the teen-friendly look and feel of the place--the library is tremendously successful. This is certainly due to the talented library staff members, who have teamed up with classroom teachers to create a culture of critical inquiry and who approach students with respect, high expectations, and plenty of warmth and humor. For all of this to happen, of course, someone had to decide it was worth doing. That person needed to understand the power of a comprehensive library program, the value of hiring terrific teacher-librarians, and the importance of providing the full-time, six-person library staff with adequate funds--more than $45,000 annually. At Grandview High, that someone is Principal Harry Bull.
