AACR2 versus RDA: a comparison of examples

Overview of some of the changes from AACR2 to RDA

Source : yale university website Terminology: Some RDA terminology differs from that of AACR2:
AACR2	RDA
heading	authorized access point (AAP)
uniform title	preferred title; conventional collective title
physical description	carrier
sound disc, etc.	audio disc, etc.
author	creator (includes composers, librettists, lyricists)
performer	contributor
chief source	preferred sources
general material designator	content, media, and carrier type
Abbreviations: From Kathy Glennan, MLA-L, 1/17/2014 RDA generally eschews abbreviations. The primary exceptions are for: Units of measurement Abbreviations that are regularly used in resources and are commonly understood by users (e.g., "SATB", "op.") Abbreviations that a resource uses to identify itself (e.g., "BWV" instead of "Bach-Werke-Verzeichnis") Abbreviations are used only when they appear on the resource. The exceptions are no. and op. (which will be used the same way as they were in AACR2: in the title area, abbreviate only when abbreviated on the item; abbreviate in access points), thematic index numbers, voice range (SATB, etc.), and units of measurements.      Use "in." for inches; however, "cm" is no longer considered to be an abbreviation Use "stereo" and "mono" (also no longer considered to be abbreviations), but spell out other terms ("quadrophonic," etc.)
AACR2	RDA
p.	pages
ca.	approximately
i.e.	that is
acc.	accompanied
unacc.	unaccompanied
arr.	arranged
ill.	illustrations
col.	color
facsim.	facsimile
ed.	edition
S.l.	[place of publication not identified]
s.n.	[publisher not identified]
n.d.	[date of publication not identified]
Examples of some of changes to abbreviations used in the physical description (extent of item)
AACR2	RDA
3 vol.	3 volumes
ca. 200 p.	approximately 200 pages
48 [i.e. 96] p.	48, that is, 96 pages
[16] p. of plates	16 unnumbered pages of plates
Dimensions: AACR2: the system of measurement used to record dimensions varies depending on the type of resource. RDA: metric units are used. (LCPS 3.5.1.3 allows for using inches for discs (RDA 3.5.1.4.4)) Metric units: AACR2: they are considered abbreviations and are followed by a full stop (e.g., cm.) RDA: they are treated as symbols and are not followed by a full stop (e.g., cm). Examples of changes to abbreviations used in dates in authorized access points representing persons (formerly known as name headings)
AACR2	RDA	LC practice (when it varies from RDA)
b. 1825	born 1825	1825-
d. 1859	died 1859	-1859
fl.	flourished	active
ca. 1837	approximately 1837	----
1836 or 7	1836 or 1837	----
18th cent.	18th century	----
16th/17th cent.	active 16th century-17th century	----
Recording and transcribing: RDA differentiates between recording and transcribing elements.    ° Recorded elements: the found information is often adjusted    ° Transcribed elements: the data is accepted as found on the resource    ° The transcribed elements are: Element Associated MARC field title 245 ‡a, ‡b statement of responsibility 245 ‡c edition statement 250 ‡a, ‡b numbering of serials 490 ‡v production statement 264 _0 ‡a, ‡b, ‡c publication statement 264 _1 ‡a, ‡b, ‡c distribution statement 264 _2 ‡a, ‡b, ‡c manufacture statement 264 _3 ‡a, ‡b, ‡c series statement 490 ‡a New to RDA: Capitalization: RDA Appendix A: LC policy is to follow the capitalization on the resource or follow the instructions in Appendix A. Diacritics: Transcribe when they appear; not necessary to add them when they are omitted from the resource. Abbreviations: RDA Appendix B: Transcribe as found on the RDA preferred source; otherwise do not use abbreviations Other things: Parallel titles may be taken from anywhere on the resource, and are not enclosed in brackets    ° However, other title information must be taken from the same source as the title proper Statement of responsibility may be taken from anywhere on the resource    ° Transcribe title, terms of address, etc.    ° Transcribe all persons named, even when there are four or more Edition statement:    ° Abbreviations are used only when they appear on the resource    ° Use the form of numbering (e.g., Arabic, roman, etc.) that appear on the resource
Inaccuracies, omissions: AACR2: Inaccuracies are transcribed followed either by [sic] or by "i.e." and the correction in square brackets. Missing letter(s) are supplied in square brackets. RDA: Inaccuracies are transcribed as they appear on the source of information. If necessary, a note may be made correcting the inaccuracy, and the title as corrected may be recorded as a variant title if it is considered important for access. Examples AACR2 1.0F 245 10 ‡a Morton Feldmans Untiteled [sic] composition für Cello und Klavier 246 3  ‡a Morton Feldmans Untitled composition für Cello und Klavier RDA 1.7.9, 2.3.1.4 245 10 ‡a Morton Feldmans Untiteled composition für Cello und Klavier 246 3  ‡i Title should read: ‡a Morton Feldmans Untitled composition für Cello und Klavier AACR2 1.0F 245 00 ‡a Horn sonat[a]s 246 3  ‡a Horn sonats RDA 1.7.9, 2.3.1.4 245 00 ‡a Horn sonats 246 3  ‡i Title should read: ‡a Horn sonatas
Dashes, brackets AACR2: ... (ellipses) and [ ] square brackets are replace by — and ( ). RDA: The punctuation is transcribed as it appears on the source. Example Title appears on the resource as ...Huésped de las nieblas... ...Guest from the mists... for flute and piano AACR2 1.1B1F 245 10 ‡a --Huésped de las nieblas-- = ‡b --Guest from the mists-- : for flute and piano RDA 1.7.3 245 10 ‡a ...Huésped de las nieblas... = ‡b ...Guest from the mists... : for flute and piano
Chief/preferred source:
Title:
Scores Sound recordings AACR2 RDA (2.2.2.2) AACR2 RDA (2.2.2.4) caption cover colophon other preliminaries other sources cover caption masthead colophon label* embedded textual material elsewhere on the resource    (container, insert, etc.)
*Use the label:      ° even when there is a collective title elsewhere on the resource      ° only if the information found there represents the resource as a whole For multi-disc sets, use the labels collectively
Edition statement: (250 field) will now encompass elements relating to the format of music that were scattered over various areas in AACR2: ° Musical presentation statement (e.g., Score and parts), an AACR2 element tagged in the 254 field ° Statements of responsibility relating to the format of music (e.g., vocal score by [name]), currently tagged in 245/‡c ° Voice range statements (e.g., High voice)
Publication statement: A new, repeatable MARC field (264) is used for production, publication, distribution, printing, and copyright date 1st indicator: always blank 2nd indicator: 0= production (for unpublished resources) 1= publication 2= distribution 3= manufacture 4= copyright notice date (optional) Abbreviations are not used unless they appear on the resource. Place of publication: if more than one, only the first is required (2.8.2)    ° Include all hierarchies of place, e.g., New Haven, CT, USA    ° No requirement to include place in the US if the publisher is not in the US Publisher name: if more than one, on the first is required (2.8.4)    ° Use the full name as found on the resource, e.g., Theodore Presser Company, Hildegarde Publishing Company    ° Include all corporate hierarchies of the name of publisher Date of publication: record the date as found on the resource    ° LCPS 1.8.2 (first alternative) says to transcribe roman numerals and not convert to Arabic Place, name, and/or date of publication not identified on resource:    ° AACR2: [S.l.], [s.n.], [n.d.]    ° RDA: [place of publication not identified], [publisher not identified], [date of publication not identified]       ° LCPS instruction strongly encourages: supply a place of publication in brackets or date in brackets       ° Each subfield is separately bracketed: D1.2.1: When adjacent elements within one area are to be enclosed in square brackets, enclose each in its own set of square brackets. from: RDA Basics (PPT)
Publication dates and copyright (©)/phonogram () dates are different elements in RDA and the copyright date may not be used for the date of publication. If the date of publication is unknown, use [Date of publication not identified] or an estimated date in brackets, with a question mark, if necessary. Copyright/phonogram date is not required if a publication date is known. However, for music materials, it is strongly suggested that copyright/phonogram dates are included, even when they are the same as the publication date.    ° Record the latest copyright date; for recordings, prefer  dates over © dates.
Extent (RDA 3.4)/Physical description (AACR2): The number and type of units (a physical or logical constituent of a resource; e.g., a volume, audiocassette, film reel, a map, a digital file) and/or subunit (a physical or logical subdivision of a unit; e.g., a page of a volume, a frame of a microfiche, a record in a digital file)    Give the extent if the resource is complete or if the total extent is known Use the appropriate term, which may be a term from the carrier type list (3.3.1.3) or a general term (3.4.1.3) Notated music: Some terms are no longer used.
AACR2	RDA (see 7.20.13 or metadata registry for a full list of terms)
v. of music, p. of music, leaves of music	score
close score	condensed score (now used for both vocal and instrumental scores)
miniature score	study score
Examples
AACR2	RDA
16 p. of music	1 score (16 pages)
1 miniature score	1 study score
1 close score	1 condensed score
1 sound disc	1 audio disc
1 sound cassette	1 audiocassette
Physical description of sound recordings: Most terms for types of carriers used in the extent are modified. The word "sound" is discontinued to avoid confusion with content.
AACR2	RDA
sound cartridge	audio cartridge
sound disc	audio disc
piano, [etc.] roll	audio roll
sound cassette	audiocassette
sound tape reel	audio tape
sound track film reel, [cassette, etc.]	sound-track reel
Additionally, some details are given even if they are standard for the type of resource: ° type of recording: analog, digital (3.16.2.3) ° recording medium (3.16.3.3) ° playing speed (3.16.4.3) ° groove characteristic (3.16.5.3) (e.g., microgroove) ° track configuration (3.16.6.3) ° tape configure (number of tracks on an audiotape) (3.16.7.3) (e.g., 12 track) ° playback (3.16.8.3) (e.g., mono, stereo) ° special playback characteristics (3.16.9.3) (e.g., Dolby, CD audio, DVD audio, MP3, SACD) ° tape configuration (number of tracks on an audiotape) ° dimensions of cartridges and cassettes, including the width of the tape    ° metric units are used for dimensions, but RDA allows for the use of another system of measure       (e.g., inches: 4 3/4 in.)
General material designation: Three new fields (336, 337, 338) collectively replace the General material designation (245 ‡h) See Content, Media, and Carrier (RDA 6.9, 3.2, 3.3 & MARC 336-338)
Notation: indicating type of notation, even with it is staff notation, is required in RDA (7.13; see also metadata registry) and is given in the 546 field: graphic notation, letter notation, mensural notation, neumatic notation, number notation, solmization, staff notation, tablature, tonic sol-fa.
Uniform titles/Preferred titles (See also A comparison of uniform titles (AACR2) and preferred titles (RDA) In progress) Two separate steps in RDA    1. record attributes (6.2-6.26)    2. determine which attributes to use in the authorized access point (6.27-6.31) Authorized access points comprise    ° preferred name of the creator (if applicable)    ° preferred title of work (6.2.1, 6.14, 6.28.1.1-6.28.1.8)    ° additional elements to differentiate among other works/expressions (6.28.1.9-6.28.1.11) Differences from AACR2:    ° no equivalent to AACR2's "works of mixed responsibility"    ° "work(s)" in RDA refers to both individual works and compilations    ° medium of performance in access point can contain more than three elements    ° standard chamber combinations (e.g., string quartet, piano trio, etc.) are no longer used    ° use "cello" not "violoncello"    ° spell out "acc." "arr." and "unacc."    ° fewer restrictions on recording key    ° librettos and operas are considered separate works Source: RDA and Sound Recordings—A Cataloging Workshop: Cataloging with RDA—Sound Recordingswork ___________________________________________________________________________
