CODEN Service

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 is 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.
