The Oregon State University Valley Library has been open 24 hours per day, five days per week, during regular academic terms since 2010. The authors collected survey data during 2012 to explore how students used the hours and whether they perceived that the provision of 24/5 hours contributes to their academic success. Nearly 90% of the respondents believed that their use of the overnight hours made a difference in their performance. The demographic, usage, and perception of value data collected provide a useful snapshot of overnight usage in this exploratory study.
