Fees depend on the total number of pages (250 words/page) and the extent of revision required (as determined by at least two editors):

• For minor-to-moderate revisions, fees range from $5-$15 per page
  (e.g., covering general English grammar, logic flow corrections, cohesiveness)

• If more extensive revisions are required, the fee may be >$15 per page
  (e.g., in-depth English corrections, clarification of logic flow, text rearrangements, extensive rewriting and/or scientific clarification, reference reformatting)

• Historically, our average fee has been ~$15 per page (constant dollars)
  (e.g., an average of manuscripts requiring all levels of revision)

• Our revision usually requires ~7-10 days

• After we return your revised manuscript, we will send you an invoice with specific instructions regarding the payment of the fee
