AACR Anglo-American Cataloguing Rules (subsequent editions, updates, and revisions).

AACR2-compatibleDenotes the coding on a name authority record (NAR) that was in the database before AACR2 rules came into effect, but was judged to be similar enough to accept in the online catalog without being converted to AACR2 rules.  The 008/10 code is d.

BFMBibliographic File Maintenance.  In certain circumstances, NACO participants must notify their LC liaison when changing an existing heading found in LC bibliographic records.  LC staff will perform BFM on those bibliographic records.  The complete guidelines for which changes need to be reported are available online at http://www.loc.gov/aba/pcc/naco/bfmguide.html.  The NACO home page also contains a useful FAQ link on BFM; see http://www.loc.gov/aba/pcc/naco/bfmfaq.html.

BIBCO contact or BIBCO liaisonThe person within a BIBCO institution who is responsible for coordinating BIBCO activity at that particular institution and for maintaining contact with the LC Cooperative Cataloging Team (Coop).

BIBCO coordinatorA member of the LC Cooperative Cataloging Team who administers membership and training issues for the BIBCO program; often used synonymously with BIBCO contact as the lead person at a particular institution.

"Blue pages"The Library of Congress Supplement Guidelines to the MARC 21 Format for Authority Data, formerly issued in print format on blue paper.  Issued by the LC Network Development and MARC Standards Office to show which MARC elements in the standard documentation ("white pages") are not implemented by the Library of Congress system, and thus cannot be used in PCC records.

CDSCataloging Distribution Service of the Library of Congress.  Publisher and distributor of cataloging documentation and LC database files.

CIP dataCataloging in Publication data.  This information typically appears on the verso of a title page of a published item but is based on a galley of the item before it is published.

DCM Z1Descriptive Cataloging Manual (DCM), Section Z1, Name and Series Authority Records; also known as Z1, or "Yellow Pages".

Division of the World – A term used historically in the Library of Congress to reflect two situations:  1) that certain entities must be established in the NACO Authority File (LC/NAF) and others in the Subject Authority File (LCSH) by the rules appropriate for each; and 2) that until recently, most LC catalogers specialized in either descriptive rules or subject rules, and divided responsibility for establishing authority records.  For NACO catalogers, it is important to consult documentation to determine whether the entity should be established according to name authority or subject authority guidelines.  See also Subject Heading Manual (SHM), H 405.

DuplicatesName or series authority records in which the main headings match, causing a conflict that must be resolved.  If the headings are for the same entity, one record is deleted; if the headings are for two distinct entities, one or both must be changed to make both unique.

ENREarly Notice Record.  Brief, incomplete authority record input by an LC cataloger into the LC/NAF as a temporary record while the full record undergoes the complete review and input process.

FAQFrequently Asked Questions.  The PCC Web site has FAQs to help users find answers to their questions.

FieldA portion of an online record as defined in the MARC 21 format.  Fixed fields typically may contain very short strings of codes or data, while variable fields are longer, and contain access points and data transcribed directly from the item being cataloged or reference consulted.

Fixed Field See Field.

FTP File Transfer Protocol.  In a NACO context, records created in one location can be transferred electronically to another database using this procedure.

Funnel coordinatorThe leader of a funnel project who handles recruitment, communication with members, distribution of documentation, voting for PCC representatives during elections, and usually the training and review duties for funnel member institutions.

Funnel projectA group of NACO members who have joined together to contribute authority records to the shared authority file.  Frequently, individual funnel members create records in modest numbers, and consolidate their efforts to make a more significant contribution in terms of quantity.  Funnels may be based on similarities or shared expertise (e.g., NACO Music Project, ArtNACO), geographic proximity (e.g., North Dakota Project), or consortium membership (e.g., CALICO South Africa).

FY Designation for Fiscal Year (e.g., FY00, FY2003).  Based on the federal calendar, the PCC fiscal year begins October 1 and ends September 30 of the next year.

H 405 One of the instruction sheets in the LC Subject Headings Manual.  H 405 is entitled "Establishing Certain Entities in the Name or Subject Authority File."  See also Division of the World.

Heading A term that may be ambiguous in the NACO and SACO environment.  The 1XX in an authority record is defined in MARC 21 as the "heading."  However, an access point used as a main or added entry on a bibliographic record is referred to as a "heading."  An authority record as a whole is often erroneously called a "heading."

ILS Integrated library system; see also LC ILS.

Independent status The library/funnel project may contribute its records independently to the shared authority file upon reaching independent status, typically within one year.

JustificationThe practice of giving a citation in the 670 field in an authority record for the forms of a name used as the main heading and for cross references.

Non-unique nameA name authority record (NAR) with a 1XX heading that represents more than one person with the same name because there is insufficient information to make a unique NAR for each.  Also referred to as a consolidated NAR.  Synonymous with Undifferentiated personal name.

Normalization The automated process by which headings are compared for uniqueness to prevent duplicate headings and conflicts between records.  Under the rules of normalization, all diacritics and punctuation marks (except for the first comma) are removed, all letters are converted to uppercase, and modified letters are converted to their unmodified forms.  Subfield delimiters (but not subfield codes) are retained.  Headings that differ only in diacritics, marks of punctuation (except the first comma), or special characters normalize to the same form and are thus considered in conflict.  Such headings need to be further differentiated.  NACO normalization rules appear on the Web at:  http://www.loc.gov/aba/pcc/naco/normrule-2.html.  A full description is available in the DCM Z1.
