''CASSI'' stands for ''Chemical Abstracts Service Source Index''. Since 2009, this formerly print and CD-ROM compilation is available as a free online resource to look up and confirm publication information. The online CASSI Search Tool provides titles and abbreviations, [[CODEN]], [[ISSN]], [[scientific journal|publisher]], and date of first issue (history) for a selected journal. Also included is its language of text and language of summaries.<ref name=cassi/>

The range is from 1907 to the present, including both serial and non-serial scientific and technical publications. The database is updated quarterly.<ref name=cassi>{{Cite web
