Beyond CASSI

Beyond CASSI features journal title abbreviations from early chemical literature and other historical reference sources that may not be listed in the CASSI Search Tool. Marion Peters, UCLA Librarian Emeritus, compiled a list of such abbreviations. CAS would like to thank Ms. Peters for sharing this compilation to assist CASSI users in finding these important references and for her continued contributions to CASSI.
