libraries
John McDonaldCIO, Claremont University
ConsortiumMarch 6, 2013
SCELC’s Need for DATA• Nascent resource sharing program
(CAMINO)
What can I get out of this if I join?
• Interest in shared print preservation
program
What will I be obligated to keep if I join?
• Some have interest in closer collaborative
collection development
What can I stop buying or what else can I buy?
OCLC Data Analysis
• SCELC officially requested provision of print
book holdings from OCLC for a portion of its
members
• 56 SCELC schools requested (50% of
membership)
• Simple Data provided:
By OCLC Number
Holding Libraries by Symbol
OCLC Data Analysis
• 2.2 Million Books (or 2,190,464 to be exact)
• 5.5 Million Holdings (or 5,558,921 to be
exact)
Data looks a little like this…

So what? What will the data tell us…
Who makes a good resource sharing partner? Who makes a good shared print partner?
What traits can influence a Library to join a program or start a partnership?
Who do is best to collaborate with on collections in the future?

• Data has proven to be valuable in modeling potential for
resource sharing, print preservation, and collaboration
• Additional areas of analysis:
▫ Overlap and uniqueness by publication year and subject area (LC
Call Number)
▫ Paired and multiple modeled scenarios
• OCLC Data is just a snapshot in time (and already outdated)
• OCLC is hard to work with and can be expensive
Potential for this data
• Need data from members directly
▫ Could include circulation
▫ Simple data extraction should be easy and can be
supplemented by OCLC API
• Find appropriate permanent home for database
• Develop self-service tool with (close to) real time data
• Determine if new OCLC Collection Analysis tool will
provide the same or similar information
Potential Next Steps
