Citation Analysis of Theses/Dissertations
A basic analysis of sources, dates, authors for a Marine Biological Laboratory
SAIL meeting - Wilmington, N.C. - May 14, 2009
Kathleen Heil, UMCES, Chesapeake Biological Laboratory, Solomons, MD Slide2
In these tough financial times when science is becoming more interdisciplinary and subfields are expanding as are number of titles in the sciences I wanted a way to evaluate material usage.
Since most of our journals are now accessible on-line I had lost my major source of input on usage, which was re-shelving and observation.
Introduction: Slide3
Citation analysis has merits and limitations, but has many applications beyond collection development.
Although I haven’t gotten further than the collection development access at this point.
My future goal is to show institutional relatedness. (How broad or limited are our institutional connections)Slide4
CBL has always had very strong ties to the University of Maryland
1925 Founded under Dr. Truitt from Univ. of Md.
1930’s Start of summer programs1941 Sponsored by the Md. Conservation Dept and
became the chief component of the State Dept. of Research and Education
1961 Md. Legislature created the Natural Resources Institute as part of the University of Maryland
Summer Classes began as Credit courses toward degrees1973 Became part of a new Campus of the University of Maryland System - The Center for Environmental & Estuarine Studies (UMCEES)1997 Became UMCES (University of Maryland Center for Environmental Science.
Background:Slide5
Background/History (continued)
1976 Graduate students formally began work during the school year as part of their graduate school experience
The first degrees were issued in :
1976 MS under the Dept of Botany University of Maryland College Park
1981 PhD Under the Dept of Microbiology
University of Maryland College ParkSlide6
Compare and contrast literature citations from MS & PhD theses/dissertations
Identify citation patterns
Formats of materials usedMost frequently cited material
Differences between subject areas
Objective: Slide7Slide8
Use DRUM, the University of Maryland Dspace Open Access archive to pull UMCES-CBL theses/dissertations from the last 5 years.
http://www.lib.umd.edu/drum
Copy and paste references into Word and then move them into Excel.
Put each thesis/dissertation into a new tab
Sort data into uniform format: author, year, title, source.
Methodology:Slide9Slide10
Sort by year

I reviewed a merged listing of publications
After doing sort on material type
There were 40 journal titles that had over 10 citations
Range from 10 to 119
The highest used title was Environmental Science and technologySlide18
