Banned: the Golden Book of Chemisry Experiments - a commentary by Chris Brunner.

Atoms and atomiic Structure Timelines - Here are several that should fill most needs:

History of Chemistry - timeline of developments from 1700 BCE to 1940. (Columbia U)

What happened and when - a brief, annotated timeline of Chemistry

This timeline of discoveries in all the sciences provides an excellent view of how the various displines developed in concert with one another. This compilation, by Ken Kohler (which he titles Biophysical Chronology) is exceptional in the amount of detail it provides (there are many Web links), especially in the widely-neglected era of Islamic culture that fluorished during the Western "dark ages". Highly recommended!

Internet History of Science - An extensive set of links, very nicely indexed according to period and place, taken from three even larger "History" sourcebooks covering the ancient, medieval, and modern period.

History of Chemical Engineering and Chemical Technology - ECHO (Exploring and Collecting History Online) is a directory to 5,000+ websites concerning the history of science, technology, and industry. You can search it, browse it according to category, or even look at the tag cloud we've generated.

How Islam Won, and Lost, the Lead in Science - 1000 years ago, science thrived in Islamic cultures while the Western world wallowed in the dark ages.
