ACS Style Citations
The CAS Source Index (CASSI) Search Tool is an online resource intended to support researchers and librarians who need accurate bibliographic information. Use this complimentary tool to quickly identify or confirm journal titles and abbreviations for publications indexed by CAS since 1907, including serial and non-serial scientific and technical publications.
The ACS citation style was developed by the American Chemical Society. This style is used for research papers in the field of chemistry.
Always check with your professor to determine which citation style you should use before beginning your paper or project.
Before you start creating your citations, you will need to identify:
Rules for the Reference Page
General Formatting Rules
Journals, Magazines, and Newspapers
