The International CODEN Service serves the library and information service community.
CODEN are unique, six-character codes that identify serial and non-serial publications produced worldwide. CODEN are assigned not only to chemistry-related literature but to publications in all subject areas. Upon request, we can assign CODEN to serial publications or retrieve and provide CODEN previously assigned to publications. For additional information, contact:
