This paper reports on the use of undergraduate students enrolled in an Applied Anthropology course as researcher for a library use study at Brigham Young University's (BYU) Harold B. Lee Library (HBLL). This is a common practice at BYU, but has not been reported extensively in the literature. The study was carried out by the authors with the assistance of undergraduate students, the students being the researchers and was conducted in order that the HBLL could dtermine student ideas for reconfiguring some newly opened space in the Periodicals room. Using students assisted the library as well as met a curricular need in the Anthropology course. Ethnographic methods were the primary means used to gather the data. The paper asserts that the peer interaction during the data collection significantly enriched the quality of the data collected.
