Collection development is the process of selecting, acquiring, and managing resources for a library or information center. This includes books, journals, digital media, and other materials that meet the needs of the community it serves. The goal is to build a diverse and relevant collection that supports education, research, and leisure activities. Librarians and collection development specialists assess user needs, trends, and gaps in the existing collection. They consider factors such as budget, space, and the quality of materials. This ongoing process ensures that the collection remains current and valuable, adapting to changes in technology and user preferences.
