Title: Comparison of Citation Use, Link Resolver, and Vendor Statistics
Objective: Link resolvers facilitate access to available full-text articles and tabulate journal use, but users can get to the articles from other paths, so they provide only partial statistics. Vendors and publishers provide COUNTER-compliant counts of the number of articles retrieved from their platforms. If a journal is available on multiple platforms, then several sets of statistics need to be merged to get a complete count of all retrievals. Citations of research publications illustrate use for research purposes. Link resolver statistics, vendor supplied statistics, and citation counts were examined to determine how well they correlate.
Methods: For four health sciences colleges at the study university, the number of times each journal title was cited in 2010 was collected. To identify faculty authors, searches by author affiliation at the study institution were performed in the ISI Web of Science to find all articles written by faculty members in the colleges of medicine, dentistry, pharmacy, and nursing in 2010. The number of times a journal was cited was entered into spreadsheet along with the use statistics collected from the journal link resolver and vendors and publishers. Two types of correlation analysis were run on the data.
Preliminary Results and Conclusions: Each set of data was compared to each other, and both Spearman Rank Order and Pearson Product-Moment correlation coefficients were calculated to examine the degree of correlation. There was a positive correlation between the vendor statistics and link resolver data, with the publisher data showing higher use statistics overall. The results indicate link resolver data could reliably suggest high- and low-use journals, avoiding the need to systematically obtain and merge data from multiple publishers for collection development decisions. A positive correlation also exists between citation use and online use statistics when a journal is cited. However, many journals that are moderately or heavily used are not cited. Citation data as a subset may tell the library which journals are most used for research by faculty, while vendor or publisher use statistics and link resolver data reflect all types of use, including educational and clinical.
