Chemical Entities of Biological Interest (ChEBI) is a freely available dictionary of 'small molecular entities'. The term 'molecular entity' encompasses any constitutionally or isotopically distinct atom, molecule, ion, ion pair, radical, radical ion, complex, conformer, etc., identifiable as a separately distinguishable entity. The molecular entities in question are either products of nature or synthetic products used to intervene in the processes of living organisms (either deliberately, as for drugs, or unintentionally', as for chemicals in the environment). The qualifier 'small' implies the exclusion of entities directly encoded by the genome, and thus as a rule nucleic acids, proteins and peptides derived from proteins by cleavage are not included.
The Yeast Resource Center provides access to data about mass spectrometry, yeast two-hybrid arrays, deconvolution florescence microscopy, protein structure prediction and computational biology. These services are provided to further the goal of a complete understanding of the chemical interactions required for the maintenance and faithful reproduction of a living cell. The observation that the fundamental biological processes of yeast are conserved among all eukaryotes ensures that this knowledge will shape and advance our understanding of living systems.
DLESE is the Digital Library for Earth System Education, a geoscience community resource that supports teaching and learning about the Earth system. It is funded by the National Science Foundation and is being built by a community of educators, students, and scientists to support Earth system education at all levels and in both formal and informal settings. Resources in DLESE include lesson plans, scientific data, visualizations, interactive computer models, and virtual field trips - in short, any web-accessible teaching or learning material. Many of these resources are organized in collections, or groups of related resources that reflect a coherent, focused theme. In many ways, digital collections are analogous to collections in traditional bricks-and-mortar libraries.
The WURM project is a database of computed Raman and infrared spectra and other physical properties for minerals. The calculations are performed within the framework of the density-functional theory and the density-functional perturbation theory. The database is freely available for teaching and research purposes and is presented in a web-based format, hosted on the web site. It provides the crystal structure, the parameters of the calculations, the dielectric properties, the Raman spectra with both peak positions and intensities and the infrared spectra with peak positions for minerals. It shows the atomic displacement patterns for all the zone-center vibrational modes and the associated Raman tensors. The web presentation is user friendly and highly oriented toward the end user, with a strong educational component in mind. A set of visualization tools ensures the observation of the crystal structure, the vibrational pattern, and the different spectra. Further developments include elastic and optical properties of minerals.

The World Wide Molecular Matrix (WWMM) is an electronic repository for unpublished chemical data. WWMM is an open collection of information of small molecules. The "Matrix" in WWMM is influenced by William Gibson's vision of a cyberinfrastructure where all knowledge is accessible. The WWMM is an experiment to see how far this can be taken for chemical compounds. Although much of the information for a given compound has been Openly published, very little is available in Open electronic collections. The WWMM is aimed at catalysing this approach for chemistry and the current collection is made available under the Budapest Open Archive Initiative (
This database contains references to publications that include numerical data, comments, and reviews on atomic transition probabilities (oscillator strengths, line strengths, or radiative lifetimes), and is part of the collection of the NIST Atomic Spectroscopy Data Center
>>> ----This page has been archived on the Web--- <<< Environment and Climate Change Canada collects biological samples from a number of lakes and rivers across Canada in support of federally mandated programs. Environment and Climate Change Canada has collected fish and invertebrates from the Great Lakes since 1977 in support of the Great Lakes Water Quality Agreement (GLWQA). More recently, samples have been collected nationally to support Canada's Chemicals Management Plan and the Clean Air Regulatory Agenda. Environment and Climate Change Canada also maintains a specimen bank of frozen tissues which is a requirement of the GLWQA and is an integral part of departmental monitoring and research programs. The National Aquatic Biological Specimen Bank (NABSB) is located in a dedicated facility at the Canada Centre for Inland Waters in Burlington, Ontario. The NABSB holds more than 37,000 samples of fish and invertebrates collected over the last 30+ years of environmental monitoring in Canada. Research conducted using samples from the NABSB has produced more than 60 scientific publications, reports and book chapters
