Scientific research articles present complicated results and ideas. However, it is often the writing rather than the science that makes these articles difficult to read. Language editors can help scientists communicate their important findings clearly and effectively. This guide tells the editor all they need to know to help scientists navigate the publication process and get their research papers ready for publication. It explains how a research article should be structured and gives a step-by-step guide to editing each section, including tables and figures. The elements of scientific style are also explained together with common problems the editor may encounter and how to solve them.
