ScienceDirect has non-ACS chemistry journals as well as interdisciplinary journals related to chemistry. This site also has e-books available.
Includes over 2,000 journals and 35,000 books published by Elsevier Science and its subsidiary publishers, including Academic Press, Cell Press, Pergamon, Mosby, and Saunders journals. Coverage is particularly strong for the life and physical sciences, medicine, and technical fields, but also includes some social sciences and humanities.
Includes chemistry, chemical engineering, clinical medicine, computer science, earth & planetary sciences, economics, engineering, energy & technology, environmental science & technology, life sciences, materials science, mathematics, physics, astronomy.
SpringerLink has applied chemistry journals. This site also has e-books which can be downloaded by chapter or the entirety of the book.
Personal copies of some books can be purchased for $39.99 each through a service offered by Springer called MyCopy. The MyCopy offer is currently valid for over 14,000 Springer eBooks. More info about MyCopy.
PubMed Central is a repository of full-text journal articles in the bio-medical and life sciences fields. This collection of articles was started up in 2000 by the National Library of Medicine.
PubMed Central (PMC) is a free archive of biomedical and life sciences journal literature at the U.S. National Institutes of Health's National Library of Medicine (NIH/NLM). In keeping with NLMs legislative mandate to collect and preserve the biomedical literature, PMC serves as a digital counterpart to NLMs extensive print journal collection. Launched in February 2000, PMC was developed and is managed by NLMs National Center for Biotechnology Information (NCBI).
PMC has material dating back to mid- to late-1800s or early 1900s for some journals.
Collection of thousands of Pathway/Genome Databases (PGDBs), and software tools for exploring them.
Quality data curated from tens of thousands of publications:
Quality data curated from tens of thousands of publications, including curated databases for E. coli, B. subtilis, H. sapiens, and S. cerevisiae.
Computationally predicted metabolic pathways and operons.
Data integrated from other databases, including gene essentiality, regulatory networks, protein features, and GO annotations.
Provides a reference on the genomes and metabolic pathways of thousands of sequenced organisms. BioCyc PGDBs are generated by software that predict the metabolic pathways of completely sequenced organisms, predict which genes code for missing enzymes in metabolic pathways, and predict operons. BioCyc also integrates information from other bioinformatics databases, such as protein feature and Gene Ontology information from UniProt. The BioCyc website provides a suite of software tools for database searching and visualization, for omics data analysis, and for comparative genomics and comparative pathway questions.
Entire content of the print edition of the CRC Handbook. Contains frequently used data in science, including the periodical table of the elements, basic constants and units, and geophysical data. Updated annually.
From the National Library of Medicine, this collection of information "provides references covering the biochemical, pharmacological, physiological, and toxicological effects of drugs and other chemicals." This is mostly citations instead of full text articles. Coverage goes back to 1999.
This database has over 39 million chemical reactions. You can search by drawing in chemical structures and then limiting to reagent, solvent, etc. Java has to be enabled to use the drawing function.
Combined web access to Beilstein, Gmelin, and Patent Chemistry Database. Search by chemical structures or reactions to retrieve physical/chemical properties, spectra, related reactions, description of reactions as well as references to the literature in which the data appear. It also includes the synthesis planner tool.
The Swiss Institute of Bioinformatics' portal that "provides access to scientific databases and software tools in different areas of life sciences including proteomics, genomics, phylogeny, systems biology, evolution, population genetics, transcriptomics etc."
Merck Index is a reference tool that contains short entries on various compounds including drugs. The entries will contain CAS registry number, synonyms of the substances, chemical formula, molecular weight, various physical properties, and references to further information about that substance.
Manually curated database of bioactive molecules with drug-like properties. It brings together chemical, bioactivity, and genomic data to aid the translation of genomic information into effective new drugs [from the website].
