According to McColvin, Community Analysis is imperative to assess the want/need/demand of community the library serves. 

Community analysis involves information needs assessment that provides data on what information library users seek for. It usually refers to user studies, which aid in gaining insight into how, why, when, and where people seek information and use. The data collected for needs assessment aid in the preparation of collection development policy of a library, which provide the staff with the guidelines for selecting appropriate library materials.
