The Comparative Toxicogenomics Database (CTD) prototype identifies interactions between chemicals and genes in diverse organisms to advance understanding of how environmental chemicals affect human health. CTD integrates and curates gene, sequence, chemical, reference, taxonomic and Gene Ontology data to support your hypotheses about gene-chemical interactions. Our data integration and curation are in early stages [as of February 2005]. For example, to date, we have curated 21 of approximately 550 targeted genes. ... [Information of the supplier, modified]
PubMed, available via the NCBI Entrez retrieval system, was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM), located at the U.S. National Institutes of Health (NIH). Entrez is the text-based search and retrieval system used at NCBI for services including PubMed, Nucleotide and Protein Sequences, Protein Structures, Complete Genomes, Taxonomy, OMIM, and many others. PubMed provides access to citations from biomedical literature. LinkOut provides access to full-text articles at journal Web sites and other related Web resources. PubMed also provides access and links to the other Entrez molecular biology resources. PubMed provides access to bibliographic information that includes MEDLINE, OLDMEDLINE, as well as: (1) The out-of-scope citations (e.g., articles on plate tectonics or astrophysics) from certain MEDLINE journals, primarily general science and chemistry journals, for which the life sciences articles are indexed for MEDLINE. (2) Citations that precede the date that a journal was selected for MEDLINE indexing. (3) Some additional life science journals that submit full text to PubMedCentral and receive a qualitative review by NLM. ... [Information of the supplier]
PubMed Commons is a system that enables researchers to share their opinions about scientific publications. Researchers can comment on any publication indexed by PubMed, and read the comments of others. PubMed Commons is a forum for open and constructive criticism and discussion of scientific issues. It will thrive with high quality interchange from the scientific community. PubMed Commons is currently in a closed pilot testing phase, which means that only invited participants can add and view comments in PubMed. ... [Information of the supplier]
Charles Valentine Riley pioneered the field of entomology in the United States. The Charles Valentine Riley Collection, part of the National Agricultural Library's (NAL) Special Collections, illustrates Riley's vision to enhance the success of agriculture through new scientific knowledge. The collection of papers and significant artifacts, also tells the story of Riley's love of nature, his keen ability to observe relationships in nature, and his devotion to recording his observations through drawing and writing. The collection complements a number of other significant manuscripts and rare books in Special Collections such as the USDA History Collection, manuscripts of Townend Glover and William Saunders, and early publications by Riley and others which provide historians and researchers a broad picture of the field of entomology in the 1800s. ...

This database is a completely revised new edition of the "Index Litteraturae Entomologicae : Serie I : Die Welt-Literatur über die gesamte Entomologie bis inclusive 1863" published by Walther Horn und Sigmund Schenkling in 1928-1928. The most important new features are: (a) the original 25,229 citations (Horn & Schenkling 1928) have been increased to over 46,500; the extra data result from resolution of highly condensed original entries or are new; (b) over 11,300 authors, artists, engravers, etc. have been recorded separately, thus supporting searches with various spellings of the name and connecting the bibliography with the biographies; (c) over 10,300 journals, publishers etc., (called ‘sources’) have been recorded separately, thus supporting searches with various spellings of the title; dating information is included and titles are given in full; (d) parts of works, other editions, addenda, translations, etc. were cross-referenced; (e) Publication dates of the works have been revised based on secondary sources (see references); (f) the citations can be exported in text format or BibTex format; (g) users can comment on each citation and contribute to improving the database. ...
