How frequently should a librarian check and update the library collection?

Checking and updating the library collection biannually is an effective approach to maintaining its relevance and quality. This timeframe allows librarians adequate opportunity to assess the collection's strengths and weaknesses, evaluating factors such as circulation statistics, patron requests, and the condition of materials. Regular biannual evaluations ensure that outdated or less popular resources can be identified and replaced, while new materials that cater to emerging interests and trends can be acquired.

Additionally, biannual reviews align with the academic calendar for many institutions, providing a structured opportunity to refresh the collection during key times of the year, such as before the start of new semesters. This periodic assessment also enhances the overall user experience, ensuring that patrons have access to up-to-date information and diverse resources that meet their needs.
