Chemistry is a big field judged by any standard, including the proliferation of American Chemical Society (ACS) divisions. Each subdiscipline in chemistry is in turn so big, that once a chemist becomes ‘differentiated’ it’s easy to lose touch even with neighboring subdisciplines. It doesn’t have to be that way.

Quite a few American Chemical Society (ACS) divisions are celebrating their 100th anniversaries this year. While this fact may at first glance seem like just a piece of nerdy trivia, Rudy Baum, Editor-in-chief of C&E News decided to dig deeper. And what he found was the Long Tail of chemistry, alive and well - in 1908. In his editorial, Baum describes how he looked for the causes of the sudden appearance of so many ACS divisions in 1908.

Science is in the middle of a transition from print to the internet as the primary medium of communication. This transition, although a boon for many scientists, creates a host of problems for those dealing with scientific information. For example, how would you interconvert a DOI and its corresponding bibliographic reference? A previous Depth-First article discussed a screen-scraping method as one solution.

The Merck Index is one of chemistry’s most useful reference works. Organized like an encyclopedia, each entry, or “Compound Monograph,” describes a single compound complete with chemical structure, CAS Number, IUPAC name, trivial names, physical properties, and leading primary literature references describing uses.

Today’s tribute to the power of simplicity comes by way of John Jaeger, who has built one of the simplest cheminformatics Web applications ever written. His creation, CampDepict, interactively produces a raster image of a 2D chemical structure given a SMILES string, not unlike Daylight’s Depict application. CampDepict uses the Ruby Web microframework Camping.
