MAPPING      J. McRee Elrod                           11 April 2003

Mapping for OPAC display usually has be adjusted locally.  Most mapping
supplied by vendors has problems.

Following are fields to check for.  Unless otherwise noted, map to the
named OPAC field given beside the field number.  Where no subfields are
given, map all.  There are no standards for these labels, so the names in
software systems vary.  Some software will allow you to change the
names.

[A strong case can be made for suppressing the labels, and displaying
the bibliographic information in ISBD order with ISBD punctuation, like
unit catalogue card.  This creates more space of bibliographic
information. The labels are often misleading.  A 100 labeled Author may
be a composer, or a criminal defendant, for example.  A 700 labeled
Added author may be a translator, an illustrator, and editor, or even a
Festschrift honouree.]

Most fields which are not mapped may simply be left in the record.  The
only fields which should be deleted are those which apply to a particular
copy in a record acquired from an individual library's catalogue.

*means the field is indexed

001  Record sequence number*
This is a local field supplied by your software.  The previous 001 may be
moved to 035, unless it is the same as the 010.  035 is usually not
mapped nor indexed.

010  LCCN*

020  ISBN*

022  ISSN*

050  LCC and 082 DDC
Most do not map these, but some map them to "Knowledge numbers" for class
searching.

090$a  Local call number*
This field varies; some libraries use a different 09X, or a number in
the 8XX or 9XX range.

090$b Location $f Sublocation.
Field and subfield vary with system.

090$c Copies $d Volumes
Field and subfields vary with system.  Usually mapped to "Holdings";
At SLC $c has print constant "c." unless there is text other than
numbers; $d has print constant "v." unless there is text or a four digit
number (year).

090$s at SLC contains "SUP" or "AUP" for the production or print
catalogue supplements; the subfield should not be mapped.

100  Personal author*

110  Corporate author*

111  Conference*
100, 110, and 111 are usually combined in a "Author" search, along with
700, 710, 711, 800, 810, and 811.

130  Uniform title*  (as main entry)

240  Uniform title*  (as filing title after 1XX)

245$a Title* $b subtitle  $h[general material designation]  $n number
$p Part
Map to "Title".

245$c Statement of responsibility.  It should be included in the keyword
search, in part because of differences in spellings of names between
statements of responsibility and entries.

246  Alternate title*
When 1st indicator is 1, good systems display a note and vary the name
of this field based on the 246 2nd indicator: 4 = Cover title, 5 = Added
title page title, 6 = Caption title, 7 = Running title, 8 = Spine title.
Other sources of title are recorded in $i (to be printed in the
note) before the title in $a, with 1st indicator 1.  The 246 should be
indexed by the title search along with 130, 240, 245, 730, and 740.
Many libraries include 505$t, 7XX$t, 8XX$t, 780$t, 785$t, 440, 830, and
840 in the title search.

247  Previous title.*
May be found in older records for serials entered under most recent
title.  Used in current records for loose-leaf services and websites
which have changed title.  Map to "Title".

250  $a Edition  $b Statement of responsibility for edition.  Include in
keyword search.

[Between 250 and 260 there are some media specific fields: 254 music, 255
maps, 256 computer files; if you have those media, those fields should
be mapped to "Media specific information".  See also 362.]

260$a Place $b Publisher $c Date $e Place $f Manufacturer $g Date
Some map these to different named fields, others to one called
"Publishing information" or "Imprint".

Beginning September 1, 2002, it is possible to have multiple imprints,
with original publisher having 1st indicator blank, intermediate
publisher having first indicator 2, and current or last publisher having
1st indicator 3.  Vendors should develop the ability for libraries to
determine in which order they appear.  Subfield $3 (entered before $a)
gives the dates covered by that imprint.

300  Collation  $a Extent and smd  $b Illustration, etc.  $c Size  $e
Accompanying material
Since 300$a may contain pagings, volumes, or other extent, as well as
specific material designation, it is probably best not to break this
field up with labels for its parts.

362  Serial numbering/dates; usually printed between 25X and 260 on
cards

410  Old from of corporate series entry.  Cf. 810.

440  $a Series*  $v numbering

490  $a Series statement $v numbering
Some libraries do index 490 0 (not traced), but not 490 1 (traced
differently in 8XX) because that form might conflict with a cross
reference.

[All 5XX fields may simply be mapped to "Notes".  Some prefer to break
out some notes with their own labels as follows.  The list is not
exhaustive.  Those marked "+" are more likely to be separately mapped.
All 5XX should be included in keyword search.]

500  Note

501  With+

502  Thesis note

503  Bibliographic history (not in current records)

505  Contents+
Some newer enhanced 505 contents notes have subfields, e.g., $t for
title, which could be mapped to the title index; the $t would need to be
after any initial article for this to be effective.  Some systems follow
the 1st indicator for a print constant: 0 = Contents, 1 = Incomplete
contents, 2 = Partial contents.

506  Restrictions on access
Some restrictions also in 540.

507  Map scale

508  Production notes

510  Indexing

511  Performers

515  Numbering peculiarities

518  Date, time and place of event

520  Summary+

521  Target audience

525  How supplemented

530  Other physical forms

536  Funding information

538  Systems details+

546  Language of text

550  Issuing body

555  Cumulative index

580  Relation to other publications

[All 6XX fields have a second indicator for the type of subject heading:
0 = LCSH, 1 = LC Children's, 2 = Mesh, 3 = NAL, 4 = Local, 5 = NLC, 6 =
NLC French, 7 = Other (with source in $2), 8 = Local French, 9 = RVM.
You should map only the one(s) you want, or if that can't be done, delete
those you don't want.  All subfields except $2 should be mapped, in the
order in which they appear.  In some OPAC software, the repeating field
to be used for 6XX headings is called DESC or Descriptor rather than
Subject.]

Not all these subfields appear in each 6XX, but if they must be
individually listed, it is simplest to list all for each.  Remember for
600, 610, and 611 you may have an author/title subject heading, so you
may wish to also index $t and subsequent fields as subject titles.

$a$q$b$c$d$e$t$k$u$f$l$m$n$o$p$r$s$g$h$x$z$y$v

600  Personal subject*

610  Corporate subject*

611  Conference subject*

630  Title subject*

650  Subject*

651  Geographic subject*

655  Genre heading* (still usually mapped to Subject index, but intended
for a possible future genre index, which might also include 245 $h
and 6XX$v)

695 Key words in Catss, and thus used by SLC for the titles of papers
given at Canadian law symposia.  Titles are in $a, and authors in $x.
If wished, 695$a may be mapped to title index, and 695$x to author
index.  In most systems, 695, like unenhanced 505, would only be
included in a keyword or anyword index which browses the entire record.

All the subdivisions listed for 6XX except $v should also be mapped for
7XX.  700, 710, 711, 780, and 785.  These may be author/title entries;
you may wish to map $t and subsequent fields to the title index as well.

700  Personal added author*

710  Corporate added author*

711  Conference added entry*

730  Uniform title*

740  Added title*
Used for related and analytical titles.

780$t  Former title*
If 1st indicator is 0, this should also produce a note based on 2nd
indicator: 0 = Continues, 1 = Continues in part, 2 = Supersedes, 3 =
Supersedes in part, 5 = Absorbed, 7 = Separated from.

785$t  Succeeding title*
If lst indicator is 0, this should also produce a note based on
2nd indicator: 0 = Continued by, 1 = Continued in part by, 2 =
Superseded in part by, 4 = Absorbed by, 5 = Absorbed in part by, 8 =
Changed back to.

800  Personal series*  $a Author $t Title $x ISSN  $v number

810  Corporate series*  $a Corporate author  $t Title  $x ISSN  $v
number.  Map and index 410 and 810 as Series; 410$a and 810$a as Author;
410 and 810$t as Title.

830  Series*  $a Title  $x ISSN  $v number

840  Series*  $a Title  $x ISSN  $v number
