Chemistry Databases and Major Reference Works

In the chemical sciences, the primary journal and patent literature describes experiments that researchers have performed, and it is growing at an exponential rate. Article, substance, and reaction databases serve as crucial entrées into this literature, helping researchers to derive the greatest possible benefit from Penn’s extensive journal collection in chemistry and the related sciences.

Major reference works give researchers necessary background information on unfamiliar topics and allow them to compare research methods, putting them in context without having to scour the literature for primary articles. Because different sources index the literature in different ways, performing complementary searches using multiple tools will provide a more comprehensive view of a particular area of science; as a result, the main strengths of Penn's collection of chemistry databases and major reference works lie in its size and diversity.

SciFinder indexes primary and review literature in all areas of chemistry, SciFinder allows researchers to search for documents, substances, or reactions and seamlessly link to the other contexts
Reaxys’s strength lies in its collection of organic, organometallic, and inorganic substances, their extensive physical properties, and their reactions.
Cambridge Structural Database contains over 1M crystal structures of organic and organometallic substances
