21.3B. Serials and integrating resources
Remote Access Electronic Resources:
Original URI (Uniform Resource Identifier) is still active but the original resource is no longer available. If the resource located at the URI represents a completely different resource from that described in the bibliographic record (i.e., for an integrating resource, not just a subsequent iteration of that resource), make a new entry for the new resource now at the original URI. LC practice: See LCRI 9.7B for guidelines about updating the bibliographic record for the original resource.
Serials:
LC/PCC practice: Listed below are other conditions for making a new entry for a serial.
1. The title of a serial used as the uniform title heading on an entry for a translation changes.
130 0# $a Inzhenernyĭ zhurnal. Mekhanika tverdogo tela. $l English.
245 10 $a Mechanics of solids.
130 0# $a Izvestiíà. Mekhanika tverdogo tela. $l English.
245 10 $a Mechanics of solids.
2. The physical medium in which the serial is issued changes as expressed in the specific material designation in the physical description area (not a reproduction or the same serial in another manifestation, e.g., a braille edition). Such a change could be from paper to microfiche, from paper to online, etc.
245 00 $a New Zealand national bibliography.
(Issued only in paper copy through Nov. 1983)
130 0# $a New Zealand national bibliography (Microfiche)
245 10 $a New Zealand national bibliography.
(Issued Dec. 1983- only in microfiche; not a microfiche edition of paper copy issues)
However, if the option to provide a term in common usage for the specific material designation has been used in the description, do not make a new entry if the change is between terms in common usage that can both be categorized by a more general term in the specific material designation. For example, if the common term "CD-ROMs" was used in the original description and the format changes to DVD-ROMs, do not create a new entry (both carriers would have the same designation "computer optical disc" if the option at 9.5B1 were not followed).
245 00 $a AIAA meeting papers on disc $h [electronic resource].
300 ## $a computer optical discs ; $c 4 3/4 in.
500 ## $a On CD-ROMs, 1996-2007; on DVD-ROMs, 2008-
3. The edition statement changes (see rule 12.1F1) and the change indicates a change in subject matter or a change in physical medium.
Integrating Resources:
LC/PCC practice:
Updating loose-leafs. If the edition statement changes and/or if the publisher issues a new base volume or volumes, apply the following guidelines:
1. Do not make a new entry for a gradual replacement edition (i.e., the author or publisher considers the publication to be a new edition and issues a replacement title page with a new edition statement but does not issue a new base volume); update the information in the edition area and give a note about the change in the edition statement (see LCRI 12.7B9.2).
2. Generally, do not consider the following to be a new resource: a new base volume with pages having various dates in the header/footer, etc., or having other indications that the same or a different publisher has just reissued the content of an existing resource as of its latest iteration. If the resource is not yet represented in the catalog, include a "Description based on" note to clarify that the iteration being cataloged is not the first iteration of a new resource. If the edition statement changed, give a note about the new edition statement (see rule 12.7B9.2).
3. Generally, consider the following to be a new resource: a new base volume having a new date in the header/footer, etc., that is consistent throughout the base volume. If both resources lack edition statements and the main entry/title proper of the two resources are the same, in the new record supply in brackets an edition statement (e.g., using the year of publication, distribution, etc.: "[2003 ed.]") (see rule 1.2B4).
4. Generally, consider the following to be a new resource: a new base volume having pages with no revision dates but the pages in the original base volume had revision dates.
5. In case of doubt, make a new record.
Updating remote access electronic resources. If the edition statement changes (rule 12.1F1), make a new entry only if the resource described in the existing record continues to exist as a resource separate from the new resource to be cataloged.
