What is LTI?

• LTI, or Library Technologies Inc., is the vendor
  we use for maintenance of USMAIs bibliographic
  and authority files
• They send us corrected bibliographic records and
  the corresponding authority records on a monthly
  basis
• Twice a year, we get updated bibliographic and
  authority records when an authorized heading used
  in USMAI changes

How LTI Handles Series

• Bib. records 4XX fields changed to 490/8XX pair
• LTI runs the series 8XX fields against authority
  files (both LCs and their own proprietary files)
• If a match is found Series remains in 8XX
• If a match is not found Series returned to us
  in a 490 0 tag
• Note No 440 tags remain in USMAI after LTI
  processing

11
How LTI Handles Series

• LTI does not change the series tracing practice
  based on the series authority records 645 a
• Any character string sent to LTI in a 440 or 490
  will be returned to us in a 490 or 490/8XX
  pairing even if the authority record indicates
  that it should have been treated as a series-like
  phrase

12
Loading Corrected Records

• Incoming records match on Aleph System Number
• No match? Not loaded
• Corrected records from semi-annual authority
  updates overlay only authority controlled fields
• 100, 110, 111, 130, 240, 490, 600, 610, 611, 630,
  650, 651, 700, 710, 711, 730, 800, 810, 811, 830

Identifying What LTI Processed

• Look for 950 tags (examples from Sys
  2613651)
• AUTH EXTRACT c 20060505
• Went to LTI on May 5, 2006 (part of initial
  clean-up)
• AUTH RELOAD c 20060712
• Reloaded in USMAI on July 12, 2006 (part of
  initial reload)
• AUTH UPDATE c 20071009
• One or more headings fixed in semi-annual update
  loaded in USMAI on Oct. 9, 2007
• For new cataloging, AUTH EXTRACT and AUTH RELOAD
  occur on the same day

14
When to Resend a Record to LTI

• If the 950 AUTH EXTRACT and AUTH RELOAD tags are
  present
• Resend if you make a substantive change to an
  authority controlled field
• Resend if you add a new authority controlled
  field
• Do not resend if the change is now represented as
  a x-ref in the authority record
• Do not resend if the only change is the addition
  of a death date to a personal name, which is
  already in the NAR
• Exercise restraint if in doubt, do not resend
