The Library web page for Chemistry is a gateway which aims to make it easier for you to choose appropriate print or electronic data sources. So use it as your starting point. For example, if you're looking for a melting point or dissociation constant of an organic compound you could look under Data collections and techniques which describes brief handbooks such as Lange's handbook of chemistry , more comprehensive sets of data such as the Journal of physical and chemical reference data , Web sources such as the NIST Chemistry WebBook or the data search engine ChemFinder . You can link directly to Web sources or to details of the Library's databases. The Dictionary can be searched by name, formula, structure and property and includes common data and a few significant literature references for each compound.
Instructions are on the guides stand nearby.
