Two Tasks in One Project

Why do RDA conversion
on legacy data?
• Such projects typically performed as a part of a
bigger project, such as backfile authorities
processing, or migration to a new system
• Consistency works best for a unified catalog,
especially with use of a discovery layer
• Doing a migration without data cleanup, performing
authorities processing without RDA conversion can
be compared to putting lipstick on a pig
Reasons driving Occidental and CSU Los
Angeles
• Long standing tradition of “authority control”
to facilitate discovery
• Limited efforts at authority control over time at
both universities
• Participation in “union” or shared catalogs
Background work begins early
for such a project
• Ascertain that loaders are in place for export
and re-import of data. Need bib control
number in records for overlay
• Tag tables are modified for RDA fields or
other new data (e.g. Tables of Contents)
• Decide what to do with that GMD!
• Evaluate profile options
CMC: Content, Media, Carrier
• Determine if standard CMC (336, 337, 338)
are what is desired. Built from fixed fields
and other variable fields
• Alternatively, can request customized CMC
fields built from holdings or other criteria
MARC Load Tables
Default bib export table
Commonly-used bib load table
Subject Authority Load Profile
Authority indexing rules table
We chose customized CMC creation
• Our records had inadequate or outdated info
about the material type of the work
• Supplied MARCIVE with item records containing
item type data
• Not a perfect solution
• For most items, a very helpful technique to build
meaningful 33X fields
• A combo solution: some records lacked 945 $
fields, so fixed field values were used for those to
create CMC fields

What records should be excluded?
Volatile or brief records were left out
 Safari Books
 ebrary
 Other records associated with database
subscriptions
Testing phase
•
•
•
•
•
Stop making changes to bibs, but continue to catalog
Load both bibs & authorities into Millennium/Sierra
Examine how profile decisions affected results
Can’t review every record, but look for patterns
Report questions/errors to vendor. Second test may
be necessary
Prep work
• Indexing issues. III involved in creating a
load table for authorities
• Purchased an index for ARN (Authority
Record numbers)
• Deleted old authority records
Ongoing maintenance: Authority records
•
•
•
•
Delete records
Load new/changed records
Update affected bib records
Work with vendor reports to resolve
issues
Ongoing maintenance: Sending new bib
records
•
•
•
•
Requires thoughtful use of Create Lists
Focus on records created since list shipment
Exclude non-volatile records
Use Export function in Data Exchange to
build a file of records to FTP to MARCIVE
• Files sent by 2pm CST are returned next
business day
Other maintenance
• On a regular basis (as determined by the
Library) should send ARN’s representing
records no longer needed to MARCIVE to
delete from history file
• Can produce a list by running Blind Headings
Report
Other enrichment can be added during
this process
Tables of Contents at $.50/hit
Summaries ($.30/hit)
Fiction/Biography data ($.50/hit)
Author notes (free)
Reading notes (Lexile, Accelerated
Reader, Reading Counts) are free
