92 Volumes of Writing on Chemistry
In his Commentary, Reuben Hudson discusses Similarities between Scientific and Dramatic Prose. This serves as a reminder that writing and communicating ideas are at the heart of JCE (and we mourn the recent loss of William Zinsser, author of the book On Writing Well in which he encouraged writers to “simplify your language and thereby find your humanity”). If you are considering writing an article for JCE, there are numerous author resources available on JCE’s ACS Web site, including recently updated:
With 92 volumes of the Journal of Chemical Education to explore, you will always find something useful—including all of the articles mentioned above, and many more, in the Journal of Chemical Education. Articles that are edited and published online ahead of print (ASAP—As Soon As Publishable) are also available.
