However, to achieve real societal developmont tnrough public libraries, flexibility in library management is needed to adapt fast to the changes in services tnat needed by the societies tnat library servo. Caen library system is required to adapt and changing its services based on the users' educational, cultural, and social needs. The problem always lies, on the, bureaucratic, and centralized library management systems tnat prohibit libraries from changing the services based on the users* needs. Further, the problem is clearly appears in multi~ brancntas library system tnat serve a wide range of users in mgn divers communities in terms of economic status, and social awareness. Uefining the services that provided, by library branches through centralized nagemont prohibits the management flexibility and consequently reduces the ability to ac hieve the users changing needs and consequently loses its importance to the society it serves. Un the other hand, the use of complete decentralization in managing multi-branches libraries would diminish the general shape of the library organization to act as an institution that has goals and action plans that drawn and implemented In an organizational framework.
