"Material Safety Data Sheets (MSDS) are an essential resource for those working with hazardous chemicals and include physical and chemical characteristics, hazards, safe handling, emergency and first aid procedures and more. 'Where to Find MSDS in the Internet' provides descriptions of and links to over 100 free MSDS collections available on the Internet. The sites are divided into general, government and nonprofit agencies, chemical manufacturers and suppliers, pesticides, and miscellaneous sites. The site also includes an MSDS FAQ, a glossary of common MSDS terms, over 325 relevant government regulations, suppliers and more supplementary material. There is some advertising, but it does not detract from a highly useful guide for locating free MSDS on the Internet."--"Best Free Reference Web Sites 2004," RUSA Quarterly, Fall 2004; reviewed March 6, 2004.
