Connect to Chemistry Resources via the NIH Library

Do you need chemical information? The NIH Library offers a wide selection of resources in chemistry including books, print and full-text online journals, electronic databases and Internet links. To learn how to search these resources effectively, attend the NIH Library training classes, personal tutorials or view online animated tutorials. Training schedules and links to animated tutorials are available at If you want a librarian to conduct a mediated search for you, access additional resources or conduct a chemical structure search, contact the library at 496-1080, Monday through Friday from 8:30 a.m. to 5 p.m.

For Books, search the NIH Library catalog ( to locate more than 2,700 books related to chemistry. The catalog also lists 302 print chemical journals; 135 full-text online chemical journals are available through the web page linked from the Online Journals page or found through ScienceDirect (see under Electronic Resources, Online Journals).

The library provides access to a number of Databases that index chemical publications. These databases, which include MEDLINE, Web of Science, Biological Abstracts and CHEMIDplus are accessible from the library's web page (under Electronic Resources, Databases.) Two important chemical databases are also available — Chemical Abstracts is accessible through the library's mediated search service, and Beilstein is available on a dedicated workstation.

Also useful are a number of Internet Resources such as Chemfinder (on the web page under Internet Resources, Scientific and Medical see Chemistry).

To help you choose which resource to search, below is a brief guide to the databases and Internet sites mentioned above. Remember, you can search most of these resources yourself, or you can ask a librarian to conduct a search for you. To make acquiring documents easier, both MEDLINE (via PubMed) and Web of Science have links to full-text journals and a document-ordering feature so that you can request documents directly from the library.

Beilstein is a bibliographic and chemical structure database that covers information on approximately 7 million organic substances. The citations are from the organic chemistry literature published from 1779 to the present including structures, reactions and chemical and physical properties.

Biological Abstracts ( is a comprehensive reference database in life sciences that covers biological aspects of chemistry. Chemical Abstracts Service (CAS) registry numbers and chemical names are searchable.

Chemfinder ( is an Internet index specifically tailored to store and present information about chemical substances including IUPAC Nomenclature of Organic Chemistry, chemical manufacturers information and material safety data sheets.

Chemical Abstracts, produced by CAS, indexes and abstracts the world's chemical literature and patents including biochemistry, organic chemistry, macromolecular chemistry, applied chemistry and chemical engineering. The library provides mediated searches of this database. Two versions of Chemical Abstracts, SciFinder and STN Easy, are available by personal or departmental subscription.

ChemIDplus ( provides access to structure and nomenclature authority files used for the identification of chemical substances cited in the National Library of Medicine databases. ChemIDplus has links to many biomedical resources at NLM and on the Internet for chemicals of interest. It is searchable by name, synonym, CAS registry number, molecular formula, classification code and structure.
