Domain specific languages vs Software reusable libraries

Hi

I am doing research about software reuse methods. I have read that The major problems in the utilization of such reuse libraries are in determining appropriate artifact classification schemes and in the selection of methods to effectively and efficiently search the library.

And to bypass the problems with reuse libraries, the use of specialized domain-specific languages was proposed as an alternative.

I would like to know why Domain Specific Languages are more preferable approach than reusable libraries as a good strategy to follow in software reuse filed.

Thanks,
Joe
