LTI MARC Update Changes
During authority control preprocessing, bibliographic records are updated to conform to the most current MARC format coding conventions and AACR2 cataloging standards. One Format Integration change, marked with a star (*), is optional: conversion of non-analytic 740 fields to 246 fields (see section 3. Field Conversions). Unless instructed otherwise, this change will be implemented.

Other Field Conversions
011 --> 776 In 776, set 1st indicator to 1; set 2nd indicator to blank.
Insert in 776 field, $c followed by the word "Original." Add
trailing $w containing NUC symbol in parentheses, followed by
the linking LCCN.
211 --> 246 Set 1st indicator of 0 to 2; set 1st indicator of 1 to 3. Set
2nd indicator to 3. Remove initial articles based on value of
2nd indicator in the old field and, if necessary, capitalize
first letter of remaining first word.
212 --> 246 Set 1st indicator of 0 to 2; set 1st indicator of 1 to 3.
Set 2nd ind. to 3.
214 --> 246 Set 1st indicator of 0 to 2; set 1st indicator of 1 to 3. Set
2nd indicator to 3. Remove initial articles based on value
of 2nd indicator in the old field and, if necessary,
capitalize first letter of remaining first word.
243 --> 240 Collective uniform title (243) not used by LC and discouraged by OCLC
input standards. Retag to 240 to allow field, in combination with 1xx, to
undergo authority control processing.
265 --> 037 Changed to 037. Data in $a is moved to $b. 037 indicator values
are set to blank.
305 --> 300 LTI distinguishes pre-AACR vs AACR coding by looking for
obsolete subfield codes and at the contents of $b and $c. If
non-ISBD, data from $c, $d, $e, & $f are combined into $b, and
original $b is changed to $c. When original 305 reflects AACR2
coding, data is retained in $a, $b, and $c. In addition, $m is
moved to 028 field $a, with 028 1st indicator set to 0 and 028
2nd indicator set to 1. Further, $n is moved to 028, with 028
1st indicator set to 1 and 028 2nd indicator set to 1. Multiple
028 fields are created if a record contains both 305 $m and 305
$n.
582 --> 580 If 1st indicator in 582 is blank, add "Related files":
before contents of $a. Change 1st indicator of 580 to blank.
740 --> 246* Retag 740 with 2nd indicator of 0, 1, or 3 to 246; in 246
field assign 1st indicator to 3 and 2nd indicator to blank.
Remove initial articles based on value of 1st indicator in the
old field and, if necessary, capitalize first letter of
remaining first word.
In accord with current LC and OCLC practice, following authority
control: 1) brackets are added surrounding GMDs ($h) in 245,
246, and 740 fields; and 2) GMDs ($h) in these same fields are
corrected to current AACR2 forms.
* Optional Format Integration change.
