LTI AUTHORITY PROCESSING
Library Technologies, Inc. (LTI) is Columbia's vendor for authority
control. For a full explanation of authority control and the services
offered by LTI go to the company website
On or about the Monday that follows the 15th of each month, records
updated from the beginning to the end of the previous month are sent
to LTI for automated authorities processing (AUP Level II). Records may be
new Precat records or fully cataloged CLIO records or records with any
change in the bibliographic record.. Active records with call
numbers are considered to be cataloged.
Names, uniform titles, series and LC subject headings (1XX, 240, 4XX, 6XX, 7XX, 8XX) are
verified against the Library of Congress authority file. LTI supplies
CLIO with new and updated authority records and replacement bibliographic
records whenever a heading or a subdivision changes.
For this to work, LTI must always have the most up-to-date version of our
bibliographic record. To accomplish this, CLIO bibliographic records are
automatically resent to LTI every time a change is made in the record. The
trigger for this is a new date in the bibliographic record history field.
Certain categories of records are not sent to LTI, e.g., suppressed
records, acquisitions records and some categories of vendor records.
Codes in the 965
field may prevent output to LTI.
Records that have been processed by LTI have the marker AUTH in a 900
field in the bibliographic record and LTI is automatically coded as
an operator with replace actions in the history tab.
LTI processing does not cause records to be automatically resent to
Prior to beginning LTI processing, a series of automated alerts described
in the following paragraphs are sent to catalogers. While bibliographic
records are being processed by LTI they should not be edited at all
including minor edits or the addition of statistics fields. When
records requiring updates are being processed by LTI, a placeholder
record remains in CLIO. When LTI returns the processed records to
us, the placeholder records are overlaid with the changed records. Edits
on a placeholder record are lost.
Note: Edits may be made to existing cataloged holdings and item
records at any time since these records are not sent to LTI.
Automated alerts are sent to all catalogers when LTI processing is taking

The second message has the subject LTI
PROCESSING HAS BEGUN. The
message gives the date range of records out for authority
processing. If you are editing a record during this time period, check
the HISTORY tab to be sure the record is not in the effected date range.
The monthly LTI processing has now begun for bib records that were
