- Cataloging Authority Control
- Online Catalog and Database Management
2AUTHORITY CONTROL IS
- the process of maintaining consistency in the
verbal form used to represent an access point in
a catalog - the further process of providing interconnections
among names, works, and subjects which display
any significant relationship
3AUTHORITY CONTROL IS
- the process of ensuring that every entry name,
uniform title, series, or subject that is
selected as an access point for the catalog is
unique and does not conflict, by being identical,
with any other entry that is already in the
catalog or may be included at a later date.
4Goals of Authority Control
- Facilitate the identifying and collocating
functions of the catalog - Users can assume that a consistent term or phrase
will refer to a particular name, title or
subject, and that variations will be brought
together under the one form

6Problems with Personal Names
- Pseudonym or pen name
- Initialized first name
- Omitted first name
- Non-roman alphabets
- Married name vs. maiden name
- Compound surname
- Names with nobility
- Changed names
7Authority Control
- Not so difficult 66 of all authors write only
one book in one edition. But the remaining 34
can be very difficult--changing names,
variations, translations, different alphabets,
etc.
8Patterns of Chinese Names
- Lin Yu-tang
- Ching-chun Hsieh
- Nelson Chou
- Jack Kai-tung Huang
- Nancy Ou-lan Hu Chou
- Surname first
- Surname last
- Chinese first name dropped
- English first name adopted without dropping
Chinese first name - Womans married name with English first name
9Married name vs. Maiden Name
- Good example
- Elizabeth Taylor

12Authority Work
- Includes the research work and intellectual
effort involved in creating and updating
authority records - Determines if a relationship exists between names
or subject heading terms - Establishes and links the names that could refer
to the same person - Establishes relationships between subject heading
terms - Includes recording the authority data of
preferred form, variants, history, scope, and
links to other authority records
13Steps of Authority Work
- Researching for variants
- Choosing one among many
- Analyzing parts of the term
- Adding, omitting or modifying the term
- Handling special language cases
- Linking the used and the unused
- Document the process

15SYNDETIC STRUCTURE
- Means Connective and is derived from classical
Greek - Conceived by Charles Cutter who defined syndetic
catalog as that kind of dictionary catalog which
binds its entries together by means of
cross-references so as to form a whole. - Great cocktail party term
16Authority Record
- Result of authority work
- A record which shows a heading in the form
established for use in the catalog - Lists cross-references to be made to and from the
heading - Cites the sources consulted in establishing the
heading
17Authority File
- Set of authority records
- Lists the names, series and subject headings that
have been established and used in a catalog and
provides links to related subject headings,
titles and names
18Authority Files
- Needed for efficient cataloging and searching in
library networks - Reduce effort involved in entering headings
- Avoid duplication of work
- Improve the quality of catalogs
19Four Functions of Authority Files
- Authority function support consistency of
headings - Finding function provide links from variants and
other authorized headings - Information function show usage and scope of
headings - Maintenance function support manual and
automatic error detection and correction
20Advantages of Authority Control
- Collecting, recording and maintaining
authoritative forms of headings - Linking variant forms of headings together
- Providing consistency and verification upon
creating bibliographic records - Automatic verification
- Global change and correction
- Shared authority files
- Linkage between authority files and bibliographic
records
21Problems with Corporate Names
- Name change
- Names in different languages
- Variant names
- Brief form of names
- Subordinate and related bodies
22Problems with Subject Terms
- Specific vs. general
- Synonyms
- Word form
- Singular or plural
- Homographs
- Direct vs. Inverted
- Popular vs Technical
- Cats or Siamese cats
- Attire, Dress, Clothing
- Armament, Disarmament
- Apple or Apples
- Bridge, Plant, Mercury
- Surgery, Plastic or Plastic surgery
- Stamp collecting or Philately
23AUTHORITY CONTROL AND PUBLIC SERVICES

- WorldCat Records in Comparison with LCSH
Authority Records - 3 total subject string match
- 26 used by LC, but not established because of
free-floating subdivisions, geographic
subdivisions, etc. - 71 not used by LC and not established
33Future of Authority Control (cont.)

headings, topical subdivisions, period
subdivisions that have topical aspects - Geographic facet to establish names in indirect
order Massachusetts--Worcester, not Worcester
(Mass.) - Form facet to be the subdivisions now being coded
v - Chronological facet to reflect the actual time
period coverage for the resource
37How to do Authority Control
- In-house
- pre cataloging
- post-cataloging
- Vendor supplied authority control
- RFP
- Specs
- Exceptions report follow-up
38In-house Authority Control
- Pre-cataloging
- Automatic verification
- Post-cataloging
- Headings reports
- Participation in national cataloging programs
39Planning for Vendor Authority Control
- Determine records to be processed and records not
to be processed - Determine headings to be processed and headings
not to be processed - Rationalize local policy to eliminate practices
that differ from national standards/LC practices
40Products Provided by Vended Authority Control
- Corrected headings
- Authority records
- Reports
41Options for Vended Authority Control
- Correction transaction records or replacement
bibliographic records - One-time processing or ongoing processing
- Machine-only processing or processing with human
review - Off-the-shelf processing or customized processing
42Implementing Vended Authority Control
- Prepare detailed project specifications

- Establish quality assurance procedures
- Re-design cataloging and other workflows
- Create supporting documentation
- Determine changes in staffing requirements
43Authority Control is Not Magic
- Authority control is not achieved without the
requisite authority work carried out by
catalogers - Without authority control, a file cannot be
considered a catalog
44Online Catalog Maintenance

- Heading reports
- Authority control
- Transfers
- Withdrawals
- Added copies/added volumes
45Error Reports

Afro-Americans to African Americans
Underdeveloped countries to Developing countries
48Retrospective Conversion (Recon)
- Recon is the process of converting shelflist
cards into a machine-readable format based on the
MARC 21 format - Each shelflist card is matched against a vendors
MARC database(s). Matches are done by ISBN, LCCN,
then author, author/title, or title, etc. - Enhancements may be made to matched MARC records,
as specified by the library. - Matches MARC records are saved onto disks/other
media, or transferred electronically over the Web
(via FTP). - Non-matches are either keyed-in by an operator,
or sent back to the library for in-house
conversion.
49Recon Specifications
- Develop specifications for Recon. The vendor may
send you a form to specify how certain fields in
the MARC records should appear. In this case, you
complete the form and place a check mark for the
option you prefer
50Who Does the Recon?
- Vendor (outsourcing)
- Process
- Advantages
- Disadvantages
- Choosing a vendor
- In-House by staff. There are many options
- CD-ROM
- Fee-based Web services
- http//www.itsmarc.com (TLC ITS.MARC)
- http//www.booksystems.com (EZCat/Pro)
- LibraryCom (http//www.librarycom.com). Provided
by CASPR Library Systems - SUNLINK (http//www.sunlink.ucf.edu)
51Who Does the Recon?
- In-House (contd.)
- Advantages
- Disadvantages
- Issues in using MARC records from free Web-based
services - Combined conversion process
- Vendor
- In-house
- Advantages
- Disadvantages
52What Recon Method to Use?
- Decision depends on
- the type of library and its collection size
- the qualifications of existing library staff
- the timeline for completing the automation
project - the cost analysis you perform for various types
of recon methods
53Barcoding the Collection
- Types of barcodes
- Smart barcodes
- Dumb barcodes
- Specifications for barcodes
- Your recon specifications should have
specifications for smart and dumb barcodes - Smart barcodes are generated during the
conversion process - After a MARC record is found for an item, a smart
barcode is linked to the item.
54Specifications for Barcodes
- Specifications for smart barcodes should include
- compatibility with the application software
- compliance with barcode standard (symbology)
- the type indicator (e.g., 1 for materials)
- name of the library, item title, and item call
number - barcodes should be arranged by call number
- one barcode is needed for each item in a multiple
copy set - one barcode is needed for each volume in a
multi-volume set - you also may want to get two identical barcodes
per each item
55Barcoding the Collection
- Pre-requisite
- attempt to close the library
- recall checked-out items
- divide shelves into sections
- Use the smart barcodes first.
- Match each call number on the barcode with that
on the shelf before affixing the barcode - Placement of barcodes
- Print materials
- Considerations
- Placement
- Non-print materials
- Considerations
- Placement
56More on Preparing the Collection for Automation
- Weeding
- Weed the collection based on your librarys
weeding criteria - Withdraw the shelflist cards for the weeded items
so that they will not be converted and paid for. - Weeding is essential before sending the shelflist
for retrospective conversion (recon). This is
because the vendor charges for converting every
card in the shelflist into a MARC 21 format.
57More on Preparing the Collection for Automation
- Inventory
- Inventory is performed to identify items for
which no shelflist cards exist and to identify
shelflist cards for which materials are missing
or lost. - Decide on the materials to be converted
- Typically, all materials destined for recon must
have shelflist cards.
58More on Preparing the Collection for Automation
- Shelflist Analysis
- Shelflist analysis is performed to examine the
completeness and accuracy of the shelflist. - The more complete and accurate the information on
the cards is, the higher the probability is for
finding matches in MARC databases. - Shelflist analysis ensures uniformity and
consistency. - Make sure each shelflist card contains this
information - accurate bibliographic information (author,
title, publication information, etc.) - a call number and a standard prefix (R for
reference or Ref for reference, etc.) - no. of copies of an item
- no. of volumes in an item
- ISBN and LCCN

- IFLA Functional requirements of bibliographic
records 4 user needs - find, identify, select, obtain
- Erik Juls 5th need
- use
- Metadata supports productive workspaces
- Teach, research, publish, write grants
64The Online Catalog
- Present traditional catalog
- Provides access to locally owned materials
- Provides access to artifactual materials
(objects books, videos, etc.) - Provides access in the forms of pointers to
locations - Is structured as a stand-alone bibliographic tool
- Provides remote access
- Monitors transactions
65The Online Catalog (cont.)
- Present traditional catalog provides (cont.)
- Powerful searching capacities including keyword
searches and Boolean operators - Links to circulation system with detailed
holdings and status information - Integrated authority control system with
cross-references - Information on titles that are on-order or
in-process
66The Online Catalog (cont.)
- The present Web-based catalog additionally
- Provides access to materials local and elsewhere,
owned and not owned - Provides access to electronic information
- Provides electronic information itself, not only
locations (and from both free and fee-based
sources
67The Online Catalog (cont.)
- The next catalog additionally
- Will be presented as a tool integrated with other
workstation tools - Will provide a variety of tools in addition to
the bibliographic function - Will provide searching through classification
schedules (controlled vocabulary)
68Whats a Portal
- Help users easily discover what resources are
available - Help users discover what resources are most
useful for their topics - Provide cross-collection searching
- Integrate and manage search results
- Link search results to full text when possible
to services if not - Authenticate and authorize or block user access
69Whats a Portal
- Ability to query two distinct streams of
electronic resources and databases - Universal stream of unrestricted resources from
web sites targeted for quality relevance - Local stream of information, access to which is
restricted to local users by license or other
agreement - Systems which gather a variety of useful
information resources into a single, one stop
web page, helping the users to avoid being
overwhelmed by infoglut or feeling lost on the
web
70Useful information resources
- Local catalog
- Other library catalogs
- Locally licensed full-text and abstracting/indexin
g databases - Public domain abstracting/indexing databases
- Finding aids for special collections and archives
- Locally digitized resources
- Vetted Web sites
71Why are we creating portals?
- Commercial search engines are deficient because
- what they search,
- how they search, and
- the fact that they only search
- (for that matter, so are library catalogs)
- Why is that?
- Quality of information
- Brute force application of keyword searching
algorithms - Too many keywords
- Too many ways of loading up documents with
spurious keywords - Too much emphasis on simple counting when
carrying out relevance routines
72Resource discovery acrossheterogeneous objects
- You pays your money and you takes your chances
- Metadata repository
- Extension of the idea of a union catalog
- Combines metadata from many collections
- Harvested (OAI protocol) or directly contributed
- Example National Science Digital Library (NSDL)
- Federated searching
- New products from ILS vendors (generally
speaking) - Licensed resources (generally speaking)
-
73Catalog as Portal to the Internet (Thomas)
- Reduce the amount of time devoted to cataloging
of books and reallocate the time of our
bibliographic control experts to provide access
to other resources, especially electronic
resources - Increase functionality of the library
portal/catalog - Increase scope and coverage of materials
- Ensure timely access to publications
- Increase the level of access from citation to
full-text - Incorporate features such as reference linking,
recommended titles, relevance ranking,
customization and personalization that make
portals so captivating
74Catalog as Portal to the Internet (cont.)
- Libraries shouldnt go it alone. Libraries should
- Collaborate with other libraries in a coordinated
plan for the acquisition, creation of metadata,
access, and preservation of materials available
through portals - Define a clear path from the local library portal
to the larger scholars portal - Partner with developers of portals and search
engines to share experience in a constructive
way, drawing on the best each has to contribute
to effective access to information
75Catalog as Portal to the Internet (cont.)
- Dont hide our light under a bushel. Libraries
should - Advertise the features of the discovery database,
a hybrid combining some of the best features of
the catalog and the portal - Quantify the value of labor-saving features of
the portal/catalog for the community of users and
for those administering the organizations that
subsidize them and stand to benefit from them
76What Do Our Users Want?
- Our users do more work and study away from the
library - Loyal to the library, but library is only one
element in a complex information structure - Print still important, but many users rely
exclusively on electronic materials - Seamless linking from one information object to
another is expected
77What Do Libraries Want?
- Share the wealth of their resources with their
- communities
- Remain a vital resource to their communities
- Leverage investments in their collections
- Make the best use of limited budgets
- Be highly visible on the Web
- Harness new technologies
- Successfully compete with other information
- services
- Stay funded (and fundable)
78Toward a New LibraryInformation Space
- Objectives
- Unite print, digital and e-collections
- Integrate access to all library resources
- Simplify digital and resource management
- (lower costs AND improve service)
- Methods and tools
- Web-accessible lists
- New role for catalogs
- Portals
- Reference linking (OpenURL)
- E-resource management systems
79Virtues of the Catalog, and Other Virtues
- Catalogs
- Serve a defined community (focused)
- Access to structured, quality collection
(credible) - Consistency of descriptions (predictable)
- Preserved and maintained (dependable)
- Internet portals tend to lack catalogs virtues,
but - Prolific and current search results
- Better search engines and ranked displays
