Chemical Abstracts was published in print from 1907 to 2009. The Mallet Chemistry Library has a complete run from 1907 through 2001. Chemical Abstracts is shelved in the center of the library, in reference ranges R1-R5. The Collective Indexes are shelved in ranges R1-R3.
Every five years CAS published a Collective Index (CI). The 14th CI was published in 2002 and covers the years 1997-2001. The library has all Collective Indexes up to this point. They are divided into:
The Index Guide (IG) for each Collective Index period provides cross-references from commonly used chemical names to official CA Index Names (with registry numbers) used in the corresponding Chemical Substance Index. It also serves as a thesaurus of all controlled-vocabulary subject headings used in the General Subject Index. The Index Guide should always be consulted before looking up a chemical name or subject term in the Collective Indexes.
Ring Systems Handbook
The RSH leads you from a ring or cage structure to the CA Index Name and Registry Number of a ring parent compound, for searching in the Chemical Substance Index. Entries are in ring analysis order and are indexed by molecular formula and Index Name.
The Registry Handbook - Number Section was a cumulative numerical listing of all registry numbers assigned to chemical substances from 1965 forward. If you have only a registry number and need the CA Index Name for that compound, look it up here first and then use the name to consult the Chemical Substance Indexes. A corresponding Names Section (available on microfiche) provided registry numbers for several hundred thousand of the most-indexed common names.
CASSI (Chemical Abstracts Service Source Index) is the comprehensive and retrospective list of publications that have been indexed by Chemical Abstracts since it began in 1907. It includes journals, books, conferences, and other series, arranged by CA abbreviation. This is the source you use to translate journal title abbreviations into full titles for searching in the library catalog and other finding aids. CASSI is located on the Circulation Desk. It is also available in a somewhat limited form on the web.
