A periodical use study at Children's Hospital of Michigan.

A periodical use study conducted in the medical library of a pediatric teaching hospital showed that the three kinds of periodical use, circulation, reading room use, and interlibrary loan follow similar patterns within the same library. Periodicals published in the most recent five years are the most used; less than 5 percent of periodicals used were over fifteen years old. Data from the study were used in making administrative and planning decisions for the library in which it was conducted.
