Q. What is "initial bibliographic control" (IBC)?
Initial bibliographic control (IBC) encompasses all the bibliographic processing that is done on an item at the acquisitions stage, including work needed to acquire an item for the Library, as well as the processing that is performed when an item is first received. Initial searching is done to determine that an item is not already in the Library’s collections or that it has not already been received and cataloged, or that it is not already on order. A bibliographic record created at the IBC stage usually contains basic identifying information that is supplemented with additional information (authorized headings, subject analysis, classification, etc.) at a later stage in the cataloging process.
