For the development of new software software reuse plays very important role. The idea of software reuse was projected in late sixties. Software reusability is the use of engineering knowledge or artifacts from existing software components to build a new system. Reusability is the key paradigm for increasing software quality in the software development. History of software development describes that area of software reusability was not so innovative. But it is believed that software reuse is still in the development phase and has not achieved its full potential. This paper describes how far we are with softwarereuse research which can get success in the field of Software reusability.
