Research ProjectResearch Project
Joint study by OhioLINK, OhioLINK members, OhioLINK Collection Building Task Force (CBTF) and OCLC Research
The goal is to strengthen the collective collection and expand cooperative acquisitions
This project is distinct from OCLC’s collection analysis service
Much of the analysis is new or previously untested

WorldCat LinkingWorldCat Linking
Obsolete OCLC numbers were replaced, Unique LCCNs or ISBNs were used to identify an
OCLC number, Records lacking any standard number were excluded
from the study, Records from the 2007 & 2008 circulation files were
paired to determine annual circulation, Approximately 93% of the records were validated;
many of the unvalidated records were for non-book materials.
The OCLC Number is used to link the circulation records to the corresponding bibliographic record in WorldCat

ConclusionsConclusions
Limited use of non-English materials,
Unique resources widely distributed,
Circulation rates vary greatly by subject, institution, …
Collectively duplication level are high.
Next Steps
Analysis is ongoing,
What information is helpful; what isn’t?
What did we get wrong?
What did we miss?
Sharing of the data.
