An authors' editor is a language professional who works "with authors to make draft texts fit for purpose". He or she edits manuscripts that have been drafted by the author (or authors) but have not yet been submitted to a publisher for publication. This type of editing is called author editing, to distinguish it from other types of editing done for publishers on documents already accepted for publication: an authors' editor works "with (and, commonly, for) an author rather than for a publisher". A term sometimes used synonymously with authors' editor is “manuscript editor” which, however, is less precise as it also refers to editors employed by scholarly journals to edit manuscripts after acceptance (in place of the term copy editor).
Authors' editors usually work with academic authors, researchers and scientists writing scholarly journal articles, books and grant proposals. Thus, the authors' editor facilitates the academic writing process by acting before submission or peer review. Authors' editors may also help authors revise manuscripts after peer review, but once the document is accepted for publication the collaboration ends (and other editors, for example a copy editor or production editor, take over).
An author's collaboration with an authors' editor begins after a manuscript has been drafted. The manuscript must be drafted in the desired publishing language: author editing does not include translation. The manuscript must be relatively complete, as author editing does not include the tasks of drafting or writing. If authors need help conceiving, structuring or writing their text, then they require the work of a developmental editor or a writer (e.g. medical writer or technical writer).
The goal of author editing is to help authors produce a clear, accurate and effective document that meets readers' expectations and that will be favorably received by publishers, journal editors and peer reviewers. Therefore, authors' editors do both linguistic editing and substantive editing (editing of "substance", i.e. content). They improve format, structure, grammar, style, data presentation, argumentation, flow and accuracy. They query authors about unclear content, inform and educate authors about good writing techniques (called "didactic editing"), and engage authors in revising the text (they "elicit revision"). Rather than simply correct the text, they collaborate with authors by dialoging with them (through in-text comments, email, phone, internet telephony, etc.) about the content and style; examples of how they annotate texts and negotiate the acceptability of the language have been given in an essay by Burrough-Boenisch. Authors' editors may also advise authors on peer review and the publishing process, and on high-impact publishing strategies.
