"In both printed CA Issues and Indexes and computer-readable services, certain abbreviations and acronyms are automatically generated for terms in the abstract text, the keyword phrases, and the text modifying phrases for index entries. Most of these abbreviations have been used prior to 1982. Users of computer-readable services need to know these standard abbreviations and acronyms in order to be able to use them in search profiles and identify them in text.

In this document, automatically generated abbreviations and acronyms in CAS publications and services are arranged in three lists. To guide users to abbreviations they need to include in their search profiles, Listing A is arranged in the alphabetical order of the full terms which are abbreviated. Do not use periods when searching CAS abbreviations or acronyms online. To provide explanation of abbreviations encountered in text, Listing B is arranged in the alphabetical order of abbreviations and acronyms"[1].
