Title		Summary	Date	ID	Author(s)
Polymers - A Property Database		Polymers - A Property Database Polymers - A Property Database provides scientific and commercial information on polymers. Search by monomer, applications, properties (mechanical, electrical, calorimetric, solubility, or surface), or manufacturing process.   Full record	Sep 13, 2010	e1000206
PopSet Database from NLM		PopSet Database from NLM The PopSet database contains related nucleotide sequences that originate from comparative studies: phylogenetic, population, environmental (ecosystem), and mutational. Each record in the database is a set of nucleotide sequences representing the same molecule from the same species (population, mutation), different identifiable species (phylogenetic), or anonymous species from the same biological community (ecosystem). Full record	Sep 13, 2010
Probe Database from NLM		Probe Database from NLM The NCBI Probe Database is a public registry of nucleic acid reagents designed for use in a wide variety of biomedical research applications, together with information on reagent distributors, probe effectiveness, and computed sequence similarities. Full record	Sep 13, 2010
Protein Clusters Database from NLM		Protein Clusters Database from NLM The Protein Clusters database provides easy access to annotation information, publications, domains, structures, and external links and analysis tools including multiple alignments, phylogenetic trees, and genomic neighborhoods. Full record	Sep 13, 2010
Protein Database from NLM		Protein Database from NLM The Protein Database is a collection of sequences from several sources, including translations from annotated coding regions in GenBank, RefSeq and TPA, as well as records from SwissProt, PIR, PRF, and PDB. Protein sequences are the fundamental determinants of biological structure and function. Full record	Sep 13, 2010
PubChem BioAssay Database from NLM		PubChem BioAssay Database from NLM The PubChem BioAssay Database contains bioactivity screens of chemical substances described in PubChem Substance. It provides searchable descriptions of each bioassay, including descriptions of the conditions and readouts specific to that screening procedure. Full record	Sep 13, 2010
PubChem Compound Database from NLM		PubChem Compound Database from NLM The PubChem Compounds Database contains validated chemical depiction information provided to describe substances in PubChem Substance. Structures stored within PubChem Compounds are pre-clustered and cross-referenced by identity and similarity groups. Additionally, calculated properties and descriptors are available for searching and filtering of chemical structures. Full record	Sep 13, 2010
PubChem Substance Database from NLM		PubChem Substance Database from NLM The PubChem Substances Database contains descriptions of chemical samples, from a variety of sources, and links to PubMed citations, protein 3D structures, and biological screening results that are available in PubChem BioAssay. If the contents of a chemical sample are known, the description includes links to PubChem Compound. Full record	Sep 13, 2010
Smithsonian Physical Tables (9th Revised Edition) from Knovel		Smithsonian Physical Tables (9th Revised Edition) from Knovel This reference source include 901 tables of data relevant to engineering and physics. Each chapters is a separate PDF.   Full record	Sep 13, 2010	e1000002
Structure Database from NLM		Structure Database from NLM Structure Database indexes data on macromolecules such as proteins. You can view the structures, find similar structures, and see chemical interactions related to these structures. Full record	Sep 13, 2010
UniGene Database from NLM		UniGene Database from NLM UniGene provides an organized view of the transcriptome. Each UniGene entry is a set of transcript sequences that appear to come from the same transcription locus (gene or expressed pseudogene), together with information on protein similarities, gene expression, cDNA clone reagents, and genomic location. Full record	Sep 13, 2010
UniSTS Database from NLM		UniSTS Database from NLM UniSTS is a comprehensive database of sequence tagged sites (STSs) derived from STS-based maps and other experiments. STSs are defined by PCR primer pairs and are associated with additional information such as genomic position, genes, and sequences. Full record	Sep 13, 2010
