The Library of Congress will implement the 2002 edition of AACR2 on December 1, 2002. The 2002 AACR2 and its related Library of Congress Rule Interpretations (LCRI) are included in Cataloger's Desktop. Printed copies of the LCRIs have also been distributed by the Cataloging Distribution Service.
Note: Revised texts of LCRI 1.1B1, 1.4F8, 1.7B23, 12.1B2, 12.7A2, 12.7B8, 21.2A, 21.30J, and 26.5A are available by selecting this link: http://lcweb.loc.gov/catdir/cpso/de2002_ 2.html. The revised LCRIs will also be available soon in Cataloger's Desktop and in printed form.
Below are the highlights of significant changes in the 2002 AACR2 that will be seen in LC's bibliographic and authority records.
There are three changes that affect all materials:
AACR2 now provides for integrating resources in revised Chapter 12, which has been renamed "Continuing Resources." An "integrating resource" is defined as "a bibliographic resource that is added to or changed by means of updates that do not remain discrete and are integrated into the whole. Integrating resources can be finite or continuing. Examples of integrating resources include updating loose-leafs and updating Web sites." (An "updating loose-leaf" is defined as "an integrating resource that consists of one or more base volumes updated by separate pages that are inserted, removed, and/or substituted.") (App. D).
When cataloging from the first iteration of an integrating resource, the following exceptions to the basic rules for choice of access points and for transcribing bibliographic data elements are applied: (1) a title proper with a typographical error is given in its corrected form (12.1B1) and a title added entry is made for the form of the title found on the resource (LCRI 21.30J); (2) the full form is chosen as the title proper when both the acronym or initialism and its full form appear on the chief source (12.1B2, LCRI 12.1B2); the acronym/initialism form is given as other title information and a title added entry is made for it (12.1E1, LCRI 21.30J); (3) for updating loose-leafs that are not yet complete, the number of volumes, etc., is omitted before the term "(loose-leaf)" in the physical description area (12.5B1, LCRI 12.5B1). (The term "iteration" is defined as "an instance of an integrating resource, either as first published or after it has been updated" (App. D).)
When the initial cataloging is done from a later iteration, and the publication date of the first iteration can be readily ascertained, it may be given in a note. Optionally, if the publication date of the first iteration is stated explicitly on the later iteration, the publication date of the first iteration may be supplied in square brackets in the publication, etc., area. (1.4F8, LCRI 1.4F8)
Changes requiring a new record include (1) for updating loose-leaf publications, a new base volume (i.e., an in toto replacement edition); (2) for remote access integrating electronic resources, the existing resource continues to exist as a separate resource from the new resource to be cataloged; (3) resources that split; (4) resources that merge (LCRI 21.3B).
The relationship between one integrating resource and another integrating resource, or between an integrating resource and a serial, or between an integrating resource and a monograph, is generally expressed by reciprocal linking notes on both records rather than by a related-work added entry for the earlier resource on the record for the later resource (12.7B8, LCRI 12.7B8, LCRI 21.28B1).
The provisions for the descriptive cataloging of serials are included in revised Chapter 12, "Continuing Resources," but the categories of materials to be cataloged as serials have been expanded to include unnumbered monographic series and some publications of limited duration that have the characteristics of serials (e.g., a daily bulletin issued during a non-recurring meeting, a quarterly activities report of a project, an annual report of an expedition) (App. D, LCRI 1.0, 12.0A1).
For serials being cataloged from the first issue, there are several changes in bibliographic description. If the chief source has both an acronym or initialism form of the title as well as its full form, the full form is chosen as the title proper; the acronym/initialism form is given as other title information and an added entry is made for it (12.1B2, LCRI 12.1B2, 12.1E1, LCRI 21.30J). The publication date in the publication, etc., area now reflects the date of the issue published first rather than the issue designated as "first" if there is a difference in dates (1.4F8).
When cataloging a later issue with numbering that starts a new sequence with the same numbering system, and the new sequence lacks a term that would distinguish the later numbering from the earlier numbering, a new record is not created. In such a situation, there is a provision to supply a bracketed term in the language of the title (e.g., "[new ser.]"). (12.3G1, LCRI 12.3G1)
Rule 21.2A1 has been revised to cover "major changes" in a title proper: a "major change" is one in which a change in the title proper results in a new record. New rule 21.2A2 covers "minor changes" in a title proper: a "minor change" is one in which a change in the title proper does not result in a new record. The "minor change" list has been expanded to include: (1) the difference between an acronym or initialism and its full form; (2) the difference involving the name of the same corporate body and elements of its hierarchy or their grammatical connection anywhere in the title; (3) the addition to, deletion from, or change in the order of words in a list anywhere in the title; (4) the addition, deletion, or rearrangement anywhere in the title of words that indicate the type of resource such as "magazine" or "series." (21.2A; LCRI 21.2A)
When cataloging a later part of a multipart item after the creation of the record for the first part, and there has been a change in the title proper, the title proper of the first part is always retained in the title and statement of responsibility area; a note for the later title is made and a title added entry is made for it (LCRI 21.2B2, 21.30J1).
When the initial cataloging is done from a later part, a note is given containing information on which part the description is based (1.7B23, LCRI 1.7B23). If the publication date of the first published part is readily available, that date may be given in a note. Optionally, if the publication date of the first published part is stated explicitly on the later part, the publication date of the first issue can be supplied in square brackets in the publication, etc., area. (1.4F8, LCRI 1.4F8)
Monographic series also follow the new provisions for introductory words (1.1B1, LCRI 1.1B1, LCRI 26.5A), for choice of title proper when both the acronym or initialism and the full form appear together (12.1B2, LCRI 12.1B2, LCRI 26.5A), and for major and minor changes in the title proper (21.2A, LCRI 21.2A, LCRI 26.5A).
When cataloging a later issue of a numbered monographic series, and the numbering starts a new sequence with the same numbering system, but the new sequence lacks a term that would distinguish the later numbering from the earlier numbering, a new series is not established. Instead, there is a provision to supply a bracketed accompanying term in the language of the title (e.g., "[new ser.]") (1.6G1, LCRI 1.6G1).
Series that represent unnumbered multipart items are now treated like numbered multipart items: there is only one heading for the series. If there has been a change in the title proper, the title proper of the earliest issue is retained; the later title is given as reference on the series authority record. (LCRI 21.2B2, LCRI 21.3A2, LCRI 26.5A).
For Chapter 3, "Cartographic Materials," the "mathematical data area" has been renamed the "mathematical and other material specific details area" to reflect the addition of provisions for the description of electronic cartographic resources (3.3, 3.7B8). The physical description area has been expanded to include provisions for layout (3.5C2), production method (3.5C3, LCRI 3.5C3), and medium (3.5C6, LCRI 3.5C6). Revised Chapter 3 also contains a number of editorial changes.
