Serial Item and Contribution Identifier (SICI)
The SICI is a variable length code which can be used to identify both print and electronic serial publications. This new edition introduces significant changes such as the ability to identify if the serial is electronic, paper, or microformat and the identification of derivative parts of a serial. It will also accommodate proprietary numbering schemes. Changes in the title code algorithm make it easier to use, and improve the uniqueness of the SICI code for contributions.
