Collection development policies are the guiding principles that libraries adhere to when acquiring, managing, and maintaining their collections. In the academic library system, these policies are critical to ensuring the relevance, depth, and quality of resources available to support the institution's teaching, learning, and research objectives. Let's delve into the facets of a comprehensive collection development policy within modern libraries.
