Since school media centers/libraries are often used for student and staff research, the age of the books and other resources is very important to the accuracy of what students and staff are learning.
To get an overall idea of how current the collection is in school libraries in this district, compare the average age of the media center/library collection in this district with the average ages of collections in the state. If you have questions about the age of district's collection, district administrators are a good source of information about how the district allocates its instructional resources. If you have questions about how and when books are replaced, speak with the school librarian/media specialist in individual schools.
