Purposes of searching - avoid multiple representations for the same entity records in an authority database headings in a bibliographic database multiple entities represented by the same character string heading vs. heading heading vs. see reference (see reference vs. see reference generally okay)
Purposes of searching +/~ gather information to create/revise the authority record for your entity “supporting” authority records locations of conferences parent bodies see also references, such as earlier/later names iterative clarify a situation
The issues where to search? how to search? what to do with information found? I’ll go through them backwards for our policy-making discussion
Aspects to think about single straightforward policy vs. different policies for different situations new records vs. revisions UCSD entities vs. others by type of entity: person vs. corporate body vs. geographic entity by language rule vs. best practice vs. individual judgement ≡ basement and ceiling
What & why what information should we look for? what should we do with what we do find? Let’s look at the possibilities….
“Entity” what is represented in a record does not always have a 1-1 relationship to a person, corporate body, work, expression, etc. a person can have multiple separate bibliographic identities Charles L. Dodgson (mathematics) Lewis Carroll (fiction) a corporate body may go through multiple name changes
Authority database your entity represented → don’t create a new record do you have useful new information to add? if so → revise the existing record not represented → create a new record
Authority database supporting entities you already know about → analogous to the above for your main entity additional relationships between your entity and supporting entities use in the authority record for your main entity initiate authority record for each newly used supporting entity analogous to the above for your main entity
Authority database the character string for your new heading or see reference is already in the database for a different entity in normalized form! heading vs. heading → generally: break the conflict if possible make the authority record undifferentiated name or title heading vs. see reference → generally: break the conflict if possible change the reference to see also see reference vs. see reference → okay
Bibliographic database your entity additional forms used in resources information in headings used birth year fuller form of name → use in your authority record cite as appropriate, also use a different form for the heading add additional see references
Bibliographic database supporting entities you already know about → analogous to the above for your main entity additional relationships between your entity and supporting entities → as above for authority database determine predominance as instructed by various rules, LCRIs, and DCM Z1 instructions forms used language of author’s resources headings used
How method how do we search to find the above information?
Character string for the heading and for all of its see references search to find that string search to find strings whose NACO-normalized forms match the NACO-normalized form of your string OCLC normalization not always the same as NACO, such as ( ) NACO = blank OCLC = as is + NACO = as is OCLC = blank
Entity search to find reasonably expected forms cultural context example: basic personal name Sarah Minter surname(s) Minter Minter [second surname] forename(s) Sarah Sarah [middle initial or name] S. S. [middle initial or name]
Entity William Peter Browne forename(s) William Peter William P. W. Peter W. P. [without and with middle initial or name] Will Willy Bill Billy not Peter or Pete?
Entity Eduardo Rubén Saucedo Sánchez de Tagle surname(s) Saucedo Sánchez de Tagle Saucedo Sánchez Saucedo S. Saucedo Sánchez de Tagle Sánchez De Tagle Tagle
Entity corporate names symbols vs. words California. Office of Law & Legislation California. Office of Law and Legislation spelled-out words vs. abbreviations Saint Croix International Waterway Commission St. Croix International Waterway Commission expected other language forms German Blind Association Deutscher Blindenverband
Where domain universe of records which database (subset) do we search? which records do we pay attention to?
Authority records LC/NAF OCLC authorities.loc.gov III authority file UCSD records in Pactech
Bibliographic records LC LC’s own database OCLC UCSD OCLC Pactech other OCLC records
Other geographic entity → official geographic name files Canadian headings UCSD entities → UCSD website? other?
Form of heading title page form = Alejandro Torres form on p. 595 = Alejandro Torres García pre-existing record in LC/NAF: Torres, Alejandro, ǂ c Lic. no pre-existing see references in LC/NAF for: Torres, Alejandro no pre-existing bibliographic records in LC’s database LC set up as: Torres, Alejandro OCLC bibliographic database has at least 2 other people usage is: Alejandro Torres heading is: Torres, Alejandro so Ann set it up as: Torres, Alejandro ǂ q (Torres García)
Authority record for your entity cite forms not used as see references? Karen Sparck Jones vs. Karen Sparck-Jones Palm vs. palm cite additional information? to aid in understanding the nature of your entity person’s profession, degree corporate body’s purpose to provide data that could be used to resolve a future conflict person’s birth year, full form of middle name corporate body’s geographic scope, founding date
Other authority records corporate hierarchies earlier/later names other relationships additional bibliographic identities for a person
