The authors approached the problem from a unique perspective: analyzing references in published articles by funded researchers in the small but highly grant-productive IUSM Department of Psychiatry.
Principal investigators (n=22) on grants active in fiscal year 2004/05 (the most current year available) from the IUSM Department of Psychiatry were identified by the university's Department of Research and Sponsored Programs.
The final data element added was whether the IUSM Library subscribed to the title.
Impact factor compared to IUSM psychiatry faculty cited references
The average IF for JCR psychiatry category journals not cited by IUSM psychiatry researchers in their publications was 0.
IUSM Library holdings compared to IUSM psychiatry-cited references
The IUSM Libraries subscribed to 47 (61%) of the 77 JCR psychiatry category journals.
Although IUSM has a Center for Sleep Disorders, it is managed by the Department of Medicine, which may explain why Sleep has a high IF but was not highly cited by IUSM Department of Psychiatry faculty.
While the importance of these titles to IUSM psychiatry faculty working in these areas was not reflected in the IF, there was also no obvious reason why the other 3 titles (Comprehensive Psychiatry, Psychiatry Research, and Journal of Nervous and Mental Disease) ranked higher by CR.
The IUSM psychiatry faculty clearly were most often citing journals held by the library.
The authors studied were also from only one IUSM department, so the results might not be generally applicable to all IUSM researchers or to researchers at other institutions.
