records will automatically aggregate items based on an OCLC or LCCN corresponding to the title, if that identifier is in each of the item records - In some cases we may choose to add the title identifier to item records if: - the title has no LCCN or OCLC assigned - there are multiple LCCN or OCLC numbers that might apply to a title we want to unify - the record is for a series (i.e., each item may correspond to a different OCLC record) - Title records are viewable in the public interfaces at: - `Portal title list `_ - `Digital Library title list `_ - `Gateway title list `_ ..
