B16.4.1 Introduction

Apply core level cataloging to the category of books represented by catalog records in roman script following the guidelines for core level treatment stated in Appendix 1 (DCM B16.3).

B16.4.2 Physical Description Fixed Field (007)

Code for microforms according to LC practice for each microform medium.

B16.4.3 Fixed Fields (008)

Code all fixed fields and in the same manner as for full level cataloging except use value 4 in FFD 1 (Encoding level). NOTE: Records in a CIP state contain value 8 in FFD 1 until CIP verification takes place (cf. DCM B16.2.3.2). For subject fixed fields, see also SCM D 440.

B16.4.4 Variable Fields

Supply the following bibliographic data elements, which are designated by their content designation. Data elements not explicitly called for in the standard but that are added to an LC core level record are indicated by #:

# 050 in the same manner as for full level cataloging, including assigning alternate class numbers for analytics in collected sets and bibliographies classed in Z if known or readily available

100-130 as applicable and in the same manner as for full level cataloging

# 240 as applicable and in the same manner as for full level cataloging; create authority records on the same basis as for full level cataloging

245 in the same manner as for full level cataloging

246 see under 700-740

250 as applicable and in the same manner as for full level cataloging

260 in the same manner as for full level cataloging

300 in the same manner as for full level cataloging

440-490 as applicable and in the same manner as for full level cataloging

# 5XX include only those that support the identification/completeness (e.g., loose material inserted) of an item; a note whose sole purpose is to justify an added entry is not grounds for inclusion

500 for source of title if not from title page

502 for unpublished theses

# 504 as applicable and in the same manner as for full level cataloging

505 as applicable and in the same manner as for full level cataloging

533 as applicable and in the same manner as for current cataloging of microforms

020 subfields $a, $z as applicable in the same manner as for full level cataloging

6XX See also SCM D 440. If appropriate, assign at least one or two headings from the SUBJECTS file and/or the NAMES file to represent the primary subject and/or form of the work at the appropriate level of specificity. Assign headings to provide access to the essential subject focus of the work. This focus should generally correspond to the meaning of the assigned class number.

Concentrating on the primary or essential subject focus of a work means that secondary or tertiary subjects will normally not be represented in the assigned subject headings of a core level record, even if they constitute at least 20% of an item (cf. SCM H 180 sec. 1). Multiple headings may be needed to represent a compound or a multi-element topic for which a single heading neither exists nor can practically be constructed or established (cf. SCM H 180 sec. 10). Multiple headings may also be needed in situations where reciprocal headings are used, for example, [place 1]-Foreign relations-[place 2] and [place 2]-Foreign relations- [place 1], or where a standard array of headings is prescribed, for example, on biographies (cf. H1330).

For the headings that are assigned, follow the conventions applied to full level cataloging. For example, where appropriate, subdivide main headings by topical, geographic, chronological, and/or form subdivisions to bring out those aspects of the primary subject (cf. SCM H 180 sec. 16).

Assign headings at the level of specificity appropriate to the work (cf. SCM H 180 sec. 4). Establish new headings for discrete topics and named entities as they are needed.

700-740/246 Assign a complement that covers at least the primary relationships associated with a work, i.e., those relationships most likely to be thought of by users as an obvious means of access to a work. Use the following guidelines for relationships that may be less obvious:

1) Corporate bodies. Assign added entries for corporate bodies that bear significant responsibility for the work (observing the limits stated in AACR2 21.30).

2) Related works. Assign added entries for a work to which the work being cataloged is closely related (AACR2 21.30G), e.g., when cataloging adaptations (AACR2 21.10), revisions (AACR2 21.12), supplements (AACR2 21.28A1), or screenplays (AACR2 21.28A1).

3) Titles (AACR 21.30J). Assign an added entry for the title proper (245- derived) of every item not entered under title. Assign added entries for alternative titles, parallel titles, titles on added title pages, and cover titles (246-derived). When using the 246 field, assign indicator values in the same manner as for full level cataloging. For items without a collective title, assign the added entries specified in LCRI 21.30J.

4) Analytical added entries (AAC2 21.30M). Assign an analytical added entry under the heading for a work contained within an item being cataloged, e.g., when cataloging commentaries with text (AACR2 21.13) or collections covered by AACR2 21.7B, 21.7C, and 25.7.

Note that the core standard does not require that added entries be justified.
