OhioLINK’s Collection Building Task Force Charge
To reduce duplication
To increase local collection development activities
To expand the amount spent on cooperative purchases
To move beyond books…

Collection Building Task Force History
1997 Discussion began

Collection Analysis Information Needed
Is our OhioLINK collection getting more diverse?
Is duplication of titles increasing or decreasing?
What does the complete overall OhioLINK collection look like?
What books didn’t we purchase? (Not Bought in Ohio or ILL stats?)
Does the 80/20 rule (80% of users’ needs are satisfied by 20% of the collection) apply?
![Page 16: Analysis of Collection Use in the OhioLINK Library Consortium Julia A. Gammon, University of Akron Anne T. Gilliland, OhioLINK Edward T. O’Neill, OCLC.](https://reader036.fdocuments.us/reader036/viewer/2022081506/56649e5c5503460f94b548d2/html5/thumbnails/16.jpg)

OhioLINK-OCLC Research Project
Project Goal
Collect, analyze and compare book circulation data from all OhioLINK libraries
Use OCLC #, ISBN or LCCN to link circulation records to WorldCat bib records
![Page 17: Analysis of Collection Use in the OhioLINK Library Consortium Julia A. Gammon, University of Akron Anne T. Gilliland, OhioLINK Edward T. O’Neill, OCLC.](https://reader036.fdocuments.us/reader036/viewer/2022081506/56649e5c5503460f94b548d2/html5/thumbnails/17.jpg)

2. Data Collection
![Page 18: Analysis of Collection Use in the OhioLINK Library Consortium Julia A. Gammon, University of Akron Anne T. Gilliland, OhioLINK Edward T. O’Neill, OCLC.](https://reader036.fdocuments.us/reader036/viewer/2022081506/56649e5c5503460f94b548d2/html5/thumbnails/18.jpg)
18
UCB Study vs. OhioLINK Study
Similar basic design
OhioLINK study includes items that do not circulate and more kinds of books
Neither could separate Inn-Reach transactions
Each is a snapshot
![Page 19: Analysis of Collection Use in the OhioLINK Library Consortium Julia A. Gammon, University of Akron Anne T. Gilliland, OhioLINK Edward T. O’Neill, OCLC.](https://reader036.fdocuments.us/reader036/viewer/2022081506/56649e5c5503460f94b548d2/html5/thumbnails/19.jpg)
19
WorldCat Linking
For records with a valid OCLC No., the OCLC No. is used as the link
For records with an obsolete OCLC No., the obsolete OCLC No. is replaced with current OCLC No.
For records without an OCLC No. but with either a LCCN and/or an ISBN the LCCN (preferred) or the ISBN to identify the corresponding WorldCat record and find the OCLC No.
Records lacking an OCLC number, LCCN, or ISBN could not be validated
![Page 20: Analysis of Collection Use in the OhioLINK Library Consortium Julia A. Gammon, University of Akron Anne T. Gilliland, OhioLINK Edward T. O’Neill, OCLC.](https://reader036.fdocuments.us/reader036/viewer/2022081506/56649e5c5503460f94b548d2/html5/thumbnails/20.jpg)
20
Design for Data Collection
Keep output simple for libraries
Libraries output circulation information
OCLC matches with richer bibliographic information from World Cat
OCLC filters some records
![Page 21: Analysis of Collection Use in the OhioLINK Library Consortium Julia A. Gammon, University of Akron Anne T. Gilliland, OhioLINK Edward T. O’Neill, OCLC.](https://reader036.fdocuments.us/reader036/viewer/2022081506/56649e5c5503460f94b548d2/html5/thumbnails/21.jpg)
21
Testing
Testing throughout much of 2006 and early 2007
Wright State University and several community colleges
Refined instructions and matching techniques
![Page 22: Analysis of Collection Use in the OhioLINK Library Consortium Julia A. Gammon, University of Akron Anne T. Gilliland, OhioLINK Edward T. O’Neill, OCLC.](https://reader036.fdocuments.us/reader036/viewer/2022081506/56649e5c5503460f94b548d2/html5/thumbnails/22.jpg)
22
Publicity
Project needs widespread support
Sufficient notice and time to complete
Support from staff at many levels
Areas of concern
![Page 23: Analysis of Collection Use in the OhioLINK Library Consortium Julia A. Gammon, University of Akron Anne T. Gilliland, OhioLINK Edward T. O’Neill, OCLC.](https://reader036.fdocuments.us/reader036/viewer/2022081506/56649e5c5503460f94b548d2/html5/thumbnails/23.jpg)

WorldCat Linking
Validating link
The title from the OhioLINK circulation record was compared to the title from the WorldCat record
If the title from the circ record was similar to the title in the WorldCat record, the record was validated
Determining material type
Only books and manuscripts were included
Material type was based on fixed fields codes in the WorldCat records (bib lvl = m and type = a or t)
![Page 25: Analysis of Collection Use in the OhioLINK Library Consortium Julia A. Gammon, University of Akron Anne T. Gilliland, OhioLINK Edward T. O’Neill, OCLC.](https://reader036.fdocuments.us/reader036/viewer/2022081506/56649e5c5503460f94b548d2/html5/thumbnails/25.jpg)
