The purpose of this research was to look at the currency of the collection of a small public library and to determine the relationship between the amount of usage of the collection and the currency of publications in the collection. A 10% systematic sample was taken of the circulating nonfiction adult shelf list of the Franklin Public Library (FPL) in Franklin, Ohio. Biographies were excluded. The objectives of the research are to determine if the FPL circulating adult nonfiction book collection is current and to determine the relationship that exists between currency and usage of the collection. Data revealed that FPL past collection development of nonfiction materials has succeeded in meeting the currency guidelines proposed in the "Standards for Public Library Service in Ohio." The relationship between currency and usage was analyzed graphically by comparing average circulation during a 5-year time period to the age of the titles collapsed into 5-year time intervals. Data analysis revealed that titles less than 15 years old in the science and social science subject areas showed increased usage over titles greater than 15 years old.
