I won't change the spirit of your work, merely the presentation in terms of clearer, stronger writing. In a formal research paper, if your personal voice appears intrusive and your paper based on opinion rather than credible documented sources, I will point this out and offer suggestions.
Proper citation of sources according to the guidelines of your institution or publication is the responsibility of the student/writer. I will not write or format your paper, end notes, or research citations. I point out where citation appears necessary, as in "needs to be cited.”
I work with your best final draft. Errors in fact or failure to cite sources (plagiarism) are the responsibility of the writer. My service is for the student or writer who has completed the work, correctly included citations according to the requirements of his or her institution, and needs the “final eye” to catch the errors that make the difference between a B or C and an A; for theses or articles, the difference between adequate and publishable.
Editing for corporate and non-profit clients cleans up the writing, omits needless words, and tightens the presentation.
The most recent doctoral thesis (medical) I edited went from competent (he had done his research and his university supplied his documentation software) to publishable.
