Chemistry is the science of molecules. Scientific, medical, and technological phenomena ultimately are understood in terms of molecular structure and interactions.

Chemists primarily produce and read:

• research articles in scholarly journals
• chemical data, such as molecular formula, chemical name, chemical structure, reaction components - found in library databases, free online tools, and handbooks and manuals
• handbooks and manuals
• books
• patents

CRC Handbook of Chemistry and Physics (Online) (also in print in Science Reference: QD65 .H23) - A classic and extensive source for physical constants, chemical properties and other data pertaining to chemistry and physics. Data is displayed in tables; the handbook is updated annually.

These indexes and databases are the ones most likely to be relevant to research in Chemistry. See  A-Z Databases for a full list of available online databases.

• Conference Proceedings Citation Index - Science, Social Science, and Humanities​
