Informed decisions Questions: What do we want to know? Commercial products OCLC Office of Research 14 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 didnt 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? 15
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 16 2. Data Collection 17 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 18 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 19 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 20 Testing Testing throughout much of 2006 and early 2007 Wright State University and several community colleges
Refined instructions and matching techniques 21 Publicity Project needs widespread support Sufficient notice and time to complete Support from staff at many levels Areas of concern 22 Data Collection April 29-May 27, 2007 Excellent participation rate 27,002,190 item records Snapshot
23 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) 24 WorldCat Linking
