The Art of Editing

The Art of Editing is the title of the book I should try to have due to my current task. Maybe I have to know how the theory of editing (though editing is an art not a scientific thing ceunah) . Editing is not easy in environment where people write  unstructured. If I edit the writing then I change everything. Furthermore, the credit goes to the writer. But the worst thing is headache came concurrently.
