Editorial Information Accounts of Chemical Research publishes concise, critical reviews of research areas currently under active investigation. Most articles are written by scientists active in the area reviewed. Reviews may be concerned in large part with work in the author's own laboratory, providing t h a t r e l e v a n t c o n t r i b u t i o n s by o t h e r investigators are mentioned sufficiently to place the author's research in perspective. Also published are occasional articles in which t h e a u t h o r offers a critical assessment of a subject t h a t has become somewhat muddled or even controversial, and proposes unifying concepts to clarify it.
