Conclusion
No software package can meet all the requirements of a given library system. Inevitably, some compromises will be needed in work flows, input, output and report formats. Customization takes lot of time, by doing that other problems could arise. Therefore while evaluating the Library Software it is important to prioritize the requirements and make sure that the chosen software meets most, if not all the high priority requirements
