The journal Toxicological Sciences is now available online, thanks to a combined effort of the Society for Toxicology and Stanford University's HighWire Press. Toxicological Sciences publishes "research articles that are broadly relevant to assessing the potential adverse health effects resulting from exposure of human or animals to chemicals, drugs, natural products, or synthetic materials." Manuscripts are published in "all areas of toxicology" including descriptive, mechanistic, interpretive, theoretical, experimental, and observational investigations. The full text (.pdf format) of all articles is available online starting 1999, with abstracts from 1998. The Society has yet to announce when the free trial period will end, but at present, the site allows free access to all online materials, as well as a free sample issue.
