WWW Chemistry Links If you can't find what you're looking for here, you might try these other collections of chemistry-related links. Chemistry Course Materials Looking for an explanation of corrosion? Or maybe a crash course on organic nomenclature? The links in this section are devoted to courses and course topics at the secondary and lower division university level. Chemical Data These links will never replace the CRC or Beilstein, but there is some (free) data available out there. Chemical Structure Libraries Some of these libraries contain just a few specialized structures, but many are very impressive in their breadth. Most require the Chime plug-in Chemistry Journals, Usenet groups and Listservers Listed here are journals and discussion groups of primary interest to secondary and college level teachers. General science journals are in the Miscellaneous section below. Chemistry Software and Multimedia These are just a few of the many things out there that I have found useful in the classroom. Miscellaneous Chemistry/Science Links Odds and ends that didn't quite fit the above categories. Some are just for fun!
