Comments
Identifiers provide information needed to retrieve a file from the storage system, to access a bitstream within a file, or to locate a physical object.
Library of Congress Control Numbers should be verified as current in the LC catalog, then normalized by:
zero-padding the right-most number if necessary to make it 6 digits long
removing all spaces and punctuation

UNT Title Identifiers are automatically assigned when an administrator creates a title record for a series or serial
Title 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
