Chemical data as well as basic constants, units and conversion factors; general health and safety information; mathematical tables, etc. Search by substance name, molecular formula, full-text terminology, etc., or browse the text and tables.

NCBI's major databases, including PubMed, Nucleotide and Protein Sequences, Protein Structures, Complete Genomes, Taxonomy, and others.

The primary worldwide repository for biological macromolecular structure data. PDB is a major tool for studying the structures of biological macromolecules and their relationships to sequence, function, and disease.

Repository of protein sequence and function data from Swiss-Prot, TrEMBL and PIR.

ExpPasy (Expert Protein Analysis System) is the protein data server of the Swiss Institute of Bioinformatics (SIB). Much duplication of data with NCBI's Entrez Protein database, but offering some unique search tools.

The main European gateway to genetics information, offering a host of databases and tools. Some duplication with the NCBI databases, but also much that is unique.

Repository for small molecule crystal structures, with bibliographic, chemical and crystallographic data for organic, organometallic and metallic compounds. Available in O'Neill Library at Reference workstations G1 and G6 and in Merkert.
