Literary Authors: AutoDewey and LC Name
Authority File
Dewey Breakfast/Update
ALA Midwinter Meeting
January 12, 2008
Overview
LC’s AutoDewey program in literature
Issues: Adding Dewey numbers to records for literary authors
in the LC Name Authority File
LC’s AutoDewey program in literature (1)
AutoDewey takes advantage of those places where Library of
Congress Classification (LCC) and DDC are similar enough to
facilitate mapping from LCC to DDC
AutoDewey is currently limited to
Individual literary authors
Poetry, drama, & fiction
English, French, & Italian literature
LC’s AutoDewey program in literature (2)
Where one-to-one mapping is possible, AutoDewey assigns
DDC numbers automatically, based on the LCC number
Where one-to-one mapping is not possible, AutoDewey
assigns the DDC number only after the cataloger has made
one or two decisions beyond assigning the LCC number
About form (poetry, drama, fiction)
About literary period
If AutoDewey choices are not right for a work (e.g., the form
is essays), a cataloger must assign the number
One-to-one mapping (or many-to-one
mapping, if the one is DDC)
AutoDewey assigns DDC numbers automatically (with
segmentation mark)
Example:
PR1580-PR1588 Beowulf
829/.3 Beowulf
One decision beyond assigning the LCC
number
PS3550-PS3576 American literature—Individual authors—
1961-2000
811/.54 American poetry, 1945-1999
812/.54 American drama, 1945-1999
813/.54 American fiction, 1945-1999
Two decisions beyond assigning the LCC
number
PS3500-PS3549 American literature—Individual authors—
1900-1960
1900-1945
811/.52 American poetry, 1900-1945
812/.52 American drama, 1900-1945
813/.52 American fiction, 1900-1945
1945-1999
811/.54 American poetry, 1945-1999
812/.54 American drama, 1945-1999
813/.54 American fiction, 1945-1999
Literary periods: from the Manual at T3A
Use only one literary period for an author and all of the
author's works, including works that may have been
published earlier or later than the dates covered by that
period. Determine the literary period in accordance with
scholarly consensus about when an author flourished. . . .
In the absence of scholarly comment, use the weight of
bibliographic evidence to determine when an author
flourished. For example, class an author who published
one novel in 1999, one novel in 2000, one in 2001, and
one in 2002 in the literary period beginning with 2000.

Literary periods: LC’s Dewey authority file
LC’s Decimal Classification Division has card files that give
the established literary period for literary authors—card
files not accessible by AutoDewey and not available to
catalogers who assign LCC numbers and use AutoDewey,
unless they leave their work area and walk into the
Decimal Classification Division.
What is the best way to make that information available?
One possibility is to put that information in the LC Name
Authority record for the author.
LC name authority record example (1)
010
n 79060436
053 0 PS3535.O39
100 1 Roethke, Theodore, ǂd 1908-1963
Meaning of LCC number excluding cutter (not given in name
authority record):
PS3535.A-PS3535.Z American literature—Individual
authors—1900-1960—R
LC name authority record example (2)
010

053 0 PR9619.3.M32
100 1 McCullough, Colleen, ǂd 1937-

083 field in MARC 21 authorities format
083 - DEWEY DECIMAL CLASSIFICATION NUMBER (R)
$a - Classification number element—single number or beginning
number of span (NR)
$b - Classification number element—ending number of span (NR)
$c - Explanatory term (NR)
A phrase or term that specifies the topic of the
classification number when the heading is represented in
more than one place in the classification schedules.
$z - Table identification—table number (NR)
$2 - Edition number (NR)
Literary period: How to specify in 083 field?
(1)
In LC’s Dewey authority file, an author’s literary period
is shown in a way not appropriate for MARC 21
For Theodore Roethke 81X.54
For Colleen McCullough 82X.914
X represents the form
MARC Proposal 2008-01: Representation of the Dewey Decimal
Classification (DDC) System in MARC 21 formats has a $y
subfield that could be used to represent the literary
period without specifying form; for details see
http://www.loc.gov/marc/marbi/2008/2008-01.html
Literary period: How to specify in 083 field?
(2)
Alternatively, give full number, including form?
For Theodore Roethke:
083 00 $a 811.54 $2 22
For Colleen McCullough:
083 00 $a 823.914 $2 22
Potential problem: people may think that number should be
used for every literary work by that author, even works in
a different form
What other information would you like to see
in the 083 field?
Use the subfield $c - Explanatory term to give information
about the meaning of the number, e.g., caption substitute
as in WebDewey?
For Theodore Roethke:
083 00 $a 811.54 $c American poetry—1945-1999 $2 22
For Colleen McCullough:
083 00 $a 823.914 $c English fiction—1945-1999 $2 22
Literary authors: Comprehensive works
From the Manual at T3A:
Literary form
For comprehensive works, use the form with which an
author is chiefly identified, e.g., Jane Austen 823.7. If the
author is not chiefly identified with one form, use T3A—8
Miscellaneous writings plus literary period plus notation 09
from the table at T3A—81-T3A—89, e.g., use 828.91409 for
a late-20th century English author who is equally famous
as a novelist, dramatist, and poet. For an individual work,
use the form in which the work is written.
Comprehensive works information in LC’s
Dewey authority file
In LC’s Dewey authority file, an author’s comprehensive
works number is identified by an asterisk

For Colleen McCullough 823.914*
Interdisciplinary works information in LC’s
Dewey authority file
An author’s interdisciplinary number may also be marked
with an asterisk
For Václav Havel
943.7043092*
891.86254 [* for belles lettres]
How to indicate comprehensive and
interdisciplinary works information? (1)
