Mirko Petrovic was in a jam. A paper on which he was lead author — a clinical study on the prevalence of sleeping aids among elderly patients — had been rejected for publication. Reviewers said that the article's methodology was improperly structured, its data were scant and not in the right format, and its language needed polishing. Resolving the flaws would require at least two weeks of work, and he wanted to publish quickly.

Petrovic had heard about a company that offered copy-editing, formatting and in-depth scientific editing of manuscripts. Although he had never used such a service before, he decided to give it a try. He negotiated a rate of about US$300 and sent in the manuscript, along with further data. Several days later, he received the finished version. The methodology had been restructured, the new data were incorporated and reformatted and it read cleanly and smoothly. Petrovic and his co-author submitted it to the Belgian medical journal Acta Clinica Belgica, where it was promptly accepted (M. Petrovic et al. Acta Clin. Belg. 61, 119–126; 2006).


“What we got back was a huge improvement,” says Petrovic, a professor of geriatrics at the University of Ghent in Belgium. “It all went very smoothly.”

Scientists all over the world are increasingly turning to manuscript-editing services. Some authors hope to refine a paper before submitting it to a journal; others aim to correct problems that emerged in peer review. Most are looking for companies to provide a basic service, including correcting for grammar, spelling, punctuation, consistency, clarity, proper capitalization, accurate use of terms and logical presentation. Many services also correct for British or American usage and for adherence to particular style manuals, such as the Chicago Manual of Style, the American Medical Association or the American Psychological Association. A number of companies specialize in editing papers by authors whose first language is not English.

But polishing poor or sloppy English is not the only aim. Some authors, like Petrovic, want further scrutiny and revision, such as the incorporation of additional data. Others are looking for a more in-depth review of the science to check for valid protocols, methods and other issues. This can give rise to ethical quandaries related to authorship and fairness. As editing services become more common, potential users should consider the benefits, weigh their options and carefully review the accepted practices of the journals in which they hope to publish.

Editing on the rise

Although statistics aren't available on the expanding use of editing services, companies offering them claim that demand is steadily rising, and the number of such companies seems to be growing (see 'Opportunities in editing'). Tightening competition for scientific publication is a big contributor to demand, say journal editors and editing-service providers alike. More papers are coming from emerging science regions such as China, India, the Middle East and South America, swelling the overall number of manuscripts that must be reviewed — and rejected. The influx means that journal editors are recommending editing services to authors whose native language isn't English with increasing frequency.

Xiao-Fan Wang: "I deal with a lot of foreign manuscripts now, and the trend is growing."

“I deal with a lot of foreign manuscripts now, and the trend is growing — it's not going to stop,” says Xiao-Fan Wang, an associate editor at the Journal of Biological Chemistry, who says that papers from authors in China alone represent 20% of the 500–600 submissions that the journal receives each year. “I tell them, 'You need to find an editing service — not somebody who's just going to fix your grammar but who understands your work and can highlight what's important,'” says Wang.

Among the players are Nature Publishing Group (NPG) in London, which publishes Nature, and Macmillan Scientific Communication, a division of Macmillan Publishers, NPG's parent company. NPG has a service called Nature Publishing Group Language Editing (NPGLE), introduced in June 2008 largely to serve non-English-speaking authors.

Macmillan Scientific Communication, meanwhile, is developing a scientific-editing service that is set for launch early next year. The venture, say project organizers, will aim to provide in-depth editorial advice on a paper's scientific content, structure and presentation.

But scientists need to be wary when hiring editors (see 'How to choose a manuscript-editing service'). Manuscript-editing companies warn that it is easy to set up a website and difficult to tell whether the information and claims on it are valid. Authors can ask their target journal for a list of recommendations or look for them online on the journal's author resource page, says Laura Stemmle, operations director for the editing service American Journal Experts in Durham, North Carolina. She adds that an author might also ask colleagues for suggestions.

Worth the trouble?

Can an editing service actually help an author to get published? Journal editors say that it depends. If a manuscript's principal or only problem is tortured English, neither a manuscript editor nor a peer reviewer is likely to reject it, say editors. But if the paper's writing is so mangled that it is almost impossible to read, it will be rejected regardless of its scientific quality. That is when an editing service is useful before the author even tries to submit.

Jim Viccaro: "Reviewers these days are overburdened, and a properly written paper is just easier to review."

“Reviewers these days are overburdened, and a properly written paper is just easier to review,” says Jim Viccaro, editor of the Journal of Applied Physics, who routinely recommends editing services to authors.

Viccaro reads all the manuscripts received by the journal and decides whether to assign them to an associate editor for further scrutiny or to send them out for peer review at once. “Some I don't even send — I reject them out of hand. You don't want to send really bad manuscripts to reviewers. You don't want to waste their time,” he says. “If you run your paper through an editing service first, you'll clear away those problems and get a fair review. Hiring an editing service doesn't guarantee publication, but it does guarantee a review with substance.”

Editing services themselves are sensitive about the publication-guarantee issue. NPGLE, for example, has a large disclaimer at the bottom of its home page stating that use of its services in no way guarantees publication in Nature or any NPG or other journal. Most editing companies have similar disclaimers on their own websites and other materials.

The cost of manuscript-editing services is relatively high, and authors may wonder whether it is worth the outlay if there is no guarantee of publication. Prices — which vary depending on the level of service, the length of the paper and the turnaround time — can be anywhere from $250 for a 6,000-word paper with a 14- to 21-day turnaround to $5,000 for a 12,000-word paper with a 48-hour turnaround. Viccaro says that it is a worthwhile investment. “This is how an author can make sure their paper is not dismissed for the wrong reason, just because no one could understand what they were talking about,” he says. Wang maintains that directing non-English-speaking authors to editing companies before submission has allowed him to accept an extra 5–10% of papers that he would otherwise have rejected. “These services can offer a lot of value,” he says. “Not only in English, but in highlighting what the author didn't even realize was the most important part.

Marissa Carter, president of Strategic Solutions in Cody, Wyoming, says that her editing service helps two out of three authors whose papers were rejected in peer review to get published in other journals.

Carter — whose company offers services from copy-editing and formatting for style to science editing — says that she might, for example, work with an epidemiological study on exposure to inhalable environmental agents. If the paper had been criticized because the statistical analysis wasn't adjusted for smoking, Carter says that she would request more data from the authors on subject smoking history. And she might suggest that they conduct further analysis. “But I can't rescue the paper if the study is flawed,” she warns. “Sometimes authors may not have collected the data they need.”

Ethics and authorship

With more in-depth, incisive editing comes the question of ethics and authorship. Companies that offer extensive science editing, addressing such issues as flawed protocols and inadequate experiment design, invite quandaries about the attribution of authorship and fairness — not every author, after all, has the extra money to secure the advantages that come with extra assistance.

Authors have to maintain their own ethical boundaries.

Both Carter's Strategic Solutions and American Journal Experts, which has started offering what it calls 'content review' to address scientific and design flaws likely to be targets of peer review, maintain that the work they do doesn't create an ethical dilemma. Carter says she has “very strict rules” and requires that she be listed in the acknowledgements if she significantly rewrites a paper. American Journal Experts says that its content reviewers only make recommendations and identify potential problems; they are not designing the experiment or writing the paper.

“I don't believe the recommendations I make would warrant authorship status,” says Anuj Kapadia, a radiologist at Duke University in Durham, North Carolina, who also acts as a content reviewer for American Journal Experts and as a peer reviewer. Journals for which he conducts peer review include Physics in Medicine and Biology, IEEE Transactions on Nuclear Science, Analytical Chemistry and the Journal of Digital Imaging.

“I'm not telling authors how to conduct the study, I'm not telling them the methods they have to follow to reach their goal,” Kapadia says. “I'm telling them they said such-and-such but didn't demonstrate it — I'm not telling them how to demonstrate it.”

The New England Journal of Medicine addresses the authorship issue by requiring authors to disclose all writing and editing assistance and to acknowledge such assistance in their paper. “Lending one's name to an article written by another party is strictly forbidden,” says the journal's spokeswoman, Karen Buckley. Although Buckley would not discuss editorial policies, the journal may still be sensitive about allegations last year, some since refuted or retracted, of ghostwriting in several top medical journals. Ghostwriting — the unacknowledged contributions of medical or other writers, often sponsored by drug companies or other corporate entities, to scientific manuscripts published under the names of academic authors — has been a thorn in the side of the medical publishing industry for a number of years.

Such touchy issues mean that authors should be careful to determine a journal's policies before submitting a manuscript. Journals in other subjects, such as physics, are unlikely to receive the scrutiny that biological and medical-science journals undergo, says Reinhardt Schuhmann, editor of Physical Review Letters.

Ultimately, it is impossible to police authors' use of manuscript-editing services — they have to maintain their own ethical boundaries, says Schuhmann. “We often suggest that authors whose papers are not well written consult a colleague,” he says. “If the colleague were someone they paid, how would we know? We don't keep track of whether they send it to an editing service.

In general, a scientist's budget, needs and time will dictate whether to hire an editing service. But authors might also keep in mind a point on which journal editors agree — a well written paper with no glaring flaws is almost certain at least to get in the door and undergo peer review, a major step towards acceptance. “We need to be confident that we're giving the scientific community high quality at all levels,” says Viccaro. “The author can help us a lot if he or she submits a manuscript that's readable.”
