An editor should possess plenty of knowledge. He should not only be well versed in grammar, but he also needs to have the habit of reading and keeping himself updated on a diverse variety of topics. This is especially true if one has hopes of becoming an academic editor. Such an individual needs to make sure that he is well versed in the different styles of languages that are used across different disciplines. There is a lot of demand for editors in the world today, especially since so many people from non-English speaking countries are doing PhDs in the English speaking world.
